E

Rather, it is the length of the sarcomere that shortens during muscle contraction.

Explanation:

The actin and myosin filaments do not shorten during a contraction. Rather the distance between the Z-lines that delimit a sarcomere shortens. It shortens because the actin and myosin fibers move antiparallel to each other hence pulling on the respective Z lines, on either side, on which they are attached.

The antiparallel movement is brought about by the ‘rowing’-like action of the myosin heads on the actin filament as they bind and release their binding sites on the actin
