Answer: C

Explanation:

Separation of duties is a security principle that requires more than one person to perform a critical task, such as authorizing a transaction, approving a budget, or granting access to sensitive data. Separation of duties reduces the risk of fraud, error, abuse, or conflict of interest by preventing any single person from having too much power or privilege. Least privilege, need to know, and due diligence are other security principles, but they do not require more than one person to perform a critical task.
