The highest level of performance or activity that an organism can maintain indefinitely without experiencing degradation or failure.
Muscle Contraction
The process whereby muscle fibers shorten or become tense due to interactions between actin and myosin filaments, generating force.
Tetanus
A bacterial disease marked by rigidity and spasms of the muscles, caused by a toxin produced by Clostridium tetani.

Final Answer :
C
Explanation :
A maximal sustained muscle contraction is called tetanus. A twitch is a single brief contraction, a threshold is the minimum stimulus needed to produce a muscle contraction, tone refers to the small amount of tension in a muscle at rest, and summation is the increase in muscle tension that results from successive stimuli before the muscle has completely relaxed.
