Which of the following security measures is usually found in a laptop?

Laptops frequently include built-in biometric readers (fingerprint scanners or facial recognition cameras) that allow users to authenticate without a password, providing a physical security layer tied to the individual user. This is a hardware-level security feature specifically designed and marketed as a laptop security measure by major manufacturers.

A bollard is a physical barrier (a post) used to prevent vehicle access to areas and is not a laptop security feature.

A hypervisor is virtualization software that runs multiple operating systems and is not a security feature specific to laptops.

Key fobs are external hardware tokens used for two-factor authentication or proximity access and are not typically built into a laptop.
