Final answer:
The correct answer is d) Password protection. Physical security measures include CCTV, security guards, and biometric scanners. Password protection is a form of logical security, not physical security.
Step-by-step explanation:
The correct answer is d) Password protection.
Physical security refers to the measures taken to protect a physical location or assets from unauthorized access, damage, theft, or any form of physical harm.
Examples of physical security include closed-circuit television (CCTV), security guards, and biometric scanners.
These measures aim to prevent or deter unauthorized access to a physical space or object.
Password protection, on the other hand, falls under the category of logical security.
It is a form of access control that restricts access to digital systems, applications, or data by requiring users to enter a password.
While password protection is an important aspect of overall security, it is not considered a physical security measure.
