EF.

The BEST physical security countermeasures to stop intruders are fencing and sensors. Let's go through each option and understand why:

A. Alarms: Alarms can be an effective way to deter intruders or notify security personnel, but they do not provide physical barriers or prevent physical access.

B. Signage: Signage can warn potential intruders that the area is off-limits, but it does not provide physical barriers or prevent physical access.

C. Lighting: Lighting can help deter intruders and make it easier to detect them, but it does not provide physical barriers or prevent physical access.

D. Mantraps: Mantraps are a physical security measure that use a series of doors or gates to trap intruders. While effective, they can be expensive to implement and maintain.

E. Fencing: Fencing is a physical barrier that can be difficult for intruders to bypass. It can be a cost-effective way to provide physical security, especially when combined with other measures such as cameras or sensors.

F. Sensors: Sensors can detect motion or other activity in the area and alert security personnel or trigger an alarm. They can be an effective way to detect and deter intruders, especially when combined with other physical security measures such as fencing.

In summary, the BEST physical security countermeasures to stop intruders are those that provide physical barriers to prevent physical access, such as fencing, combined with sensors to detect and deter intruders.
