A) the filament that move to shorten a muscle is creative phosphate
B) ultimate source of energy for muscle contraction is glucose
C) response of a muscle/nerve to a stimulus is not proportionate to its intensity
D) None of the above

It does not depend upon the intensity of the stimulus provided. At or above the threshold value a muscle fibre always contracts with maximum force irrespective of the strength of the stimulus.
