A. B. C. D.C.
The correct answer is C. RG-59.
Explanation:
Terminating a coaxial cable means attaching a connector at the end of the cable so that it can be connected to a device, such as a TV, a modem, or a router.
Out of the given options, only RG-59 is a type of coaxial cable, and it is commonly used for connecting analog CCTV cameras, as well as for some older cable TV installations. RG-59 cables typically terminate with BNC connectors, which are twist-lock connectors that provide a secure connection and good signal quality.
The other options, DB9, RJ45, and RS-232, are all types of connectors, but they are used with different types of cables.
DB9 (or DE-9) is a 9-pin serial connector that was commonly used for connecting peripherals, such as modems and printers, to computers. It is not used with coaxial cables.
RJ45 is an 8-pin connector that is commonly used for Ethernet networking. It is used with twisted pair cables, not coaxial cables.
RS-232 is a standard for serial communication that defines the signals, voltages, and connectors used for communication between computers and peripherals. It is not a type of cable or connector, but rather a protocol that can be used with various types of cables, including serial cables and Ethernet cables.
Therefore, the correct answer to the question is C. RG-59, as it is the only option that refers to a type of coaxial cable that can be terminated with a BNC connector.
