Explanation

Logical (also called technical) access controls are software- or system-based mechanisms that restrict access to data and systems. A firewall is a classic logical control - it enforces rules in software/hardware logic to permit or deny network traffic. Security guards (B) and keys/locks (C) are physical access controls that restrict physical entry. Fingerprint scanners (D) can be physical controls when used to open doors, or technical controls when used to log into a system - in most exam contexts they appear as a biometric authentication method rather than a pure logical control. Firewalls are unambiguously logical/technical.
