Answer: A

Explanation:

A technical security measure is a measure that uses technology to protect information assets from unauthorized access, modification, disclosure, or destruction. Examples of technical security measures include encryption, firewalls, antivirus software, authentication systems, and access control mechanisms. Encryption is a technical security measure that transforms information into an unreadable format using a secret key or algorithm. Encryption protects the confidentiality, integrity, and availability of information by preventing unauthorized parties from accessing or altering it. Therefore, encryption is the correct answer to this question.
