Solution

The correct option is B Tetanic contraction
If the stimuli for contraction reach a muscle at a high rate, the muscle would have no time to relax; the contractions would overlap and the muscle as a result would continuously twitch or contract. This is called tetanic twitch or tetanic contraction.
