The correct answer is A. Bollards.

Bollards are vertical posts or pillars that are installed in a row to block vehicles from entering specific areas, such as building entrances, walkways, or pedestrian zones. Bollards can be made of various materials such as steel, concrete, or plastic and can come in different shapes and sizes. They are commonly used in public spaces, parking lots, and on private property to increase safety and security.

Bollards provide physical barriers that prevent vehicles from getting too close to building entrances and exits. They can help to protect against accidental collisions, but also act as a deterrent against intentional attacks, such as ramming vehicles into buildings. Bollards are often placed strategically to create a perimeter around buildings and control the flow of traffic.

Reflective glass, security guards, and security cameras can also contribute to building security, but they do not provide physical barriers against vehicles. Reflective glass can be used to prevent people from looking inside a building, but it does not prevent vehicles from entering or approaching the building. Security guards and security cameras can be used to monitor and control access to buildings, but they cannot physically block vehicles from entering an area.
