Which of the following controls BEST ensures a user creates a complex password?

Operating system rules can be configured to enforce password complexity requirements. These rules can specify the minimum length, complexity, and expiration of passwords. By setting these parameters, the operating system ensures that users create passwords that are difficult to guess or crack, thus enhancing security.

Multi-factor authentication (B) adds an additional layer of security but does not directly ensure the creation of complex passwords. Information security awareness © is crucial for educating users about the importance of complex passwords but does not enforce their creation. Biometrics (D) is an alternative form of authentication that may replace or supplement passwords but does not govern their complexity.
