C) If maintainability is constant and reliability decreases, then availability decreases. This is because availability is a function of both reliability and maintainability. Reliability refers to the probability that a system will perform its intended function without failure for a specific period of time. Maintainability refers to the ease with which a system can be repaired or maintained. If reliability decreases (meaning the system is more likely to fail), and maintainability remains the same, the system will be less available for use because it will be failing more often and the repair or maintenance speed does not increase to compensate for the increased failures.
