C Correct answer
Explanation

A failure is the observable incorrect behavior that occurs when executing software with a fault. Faults (or bugs) are defects in the code that may remain dormant until triggered by specific inputs. Errors are human mistakes that introduce faults. Only failures are directly visible to end-users through incorrect behavior.
