B Correct answer
Explanation

To prevent password reuse, set PASSWORD_REUSE_TIME to UNLIMITED and PASSWORD_REUSE_MAX to 1. This combination ensures a password can never be reused. Setting both to UNLIMITED allows immediate reuse. Option A mentions a non-existent parameter. Password verify functions validate complexity, not reuse history.
