The most commonly used fence is the chain linked fence and it is the most affordable.

The standard is a six-foot high fence with two-inch mesh square openings.

The material should consist of nine-gauge vinyl or galvanized metal.

Nine-gauge is a typical fence material installed in residential areas.

Additionally, it is recommended to place barbed wire strands angled out from the top of the fence at a 45 angle and away from the protected area with three strands running across the top.

This will provide for a seven-foot fence.

There are several variations of the use of "top guards" using V-shaped barbed wire or the use of concertina wire as an enhancement, which has been a replacement for more traditional three strand barbed wire "top guards." The fence should be fastened to ridged metal posts set in concrete every six feet with additional bracing at the corners and gate openings.

The bottom of the fence should be stabilized against intruders crawling under by attaching posts along the bottom to keep the fence from being pushed or pulled up from the bottom.

If the soil is sandy, the bottom edge of the fence should be installed below ground level.

For maximum security design, the use of double fencing with rolls of concertina wire positioned between the two fences is the most effective deterrent and cost- efficient method.

In this design, an intruder is required to use an extensive array of ladders and equipment to breach the fences.

Most fencing is largely a psychological deterrent and a boundary marker rather than a barrier, because in most cases such fences can be rather easily penetrated unless added security measures are taken to enhance the security of the fence.

Sensors attached to the fence to provide electronic monitoring of cutting or scaling the fence can be used.

When it comes to maximum security design, a fence can be an effective and cost-effective method. However, the type of fence that is most effective and cost-effective will depend on a variety of factors, such as the level of security required, the location of the fence, and the budget available.

Out of the options provided, option C - an 8' high fence with strands of barbed wire - is the most effective and cost-effective method for maximum security design. Here's why:

  1. Height: A fence that is 8 high is significantly taller than a 3 to 4 or 6 to 7' high fence, making it more difficult for intruders to climb over.

  2. Barbed Wire: The addition of strands of barbed wire at the top of the fence adds an extra layer of security, as it can injure or deter anyone attempting to climb over the fence.

  3. Cost-Effective: While an 8' high fence with strands of barbed wire may be more expensive than a shorter fence, it is still a cost-effective method compared to other security measures such as hiring security personnel or installing surveillance cameras.

  4. Legal Considerations: It's worth noting that the use of barbed wire may be restricted by local or state laws, so it's important to consult with legal experts before installing such a fence.

Option D - double fencing - may also be effective for maximum security design, but it is likely to be more expensive than an 8' high fence with strands of barbed wire. Double fencing involves installing two fences with a gap in between them, making it more difficult for intruders to breach the perimeter. However, the cost of materials and installation for double fencing may be higher than for a single fence with barbed wire.

In conclusion, an 8' high fence with strands of barbed wire is the most effective and cost-effective method for maximum security design. However, it's important to consider other factors such as legal restrictions and the specific security needs of the location before deciding on a particular type of fence.
