False. That question doesn't really make sense also but it should still be false given the context.
When sarcomeres shorten, the muscle fiber SHORTENS.
Mechanism :
Sacromeres are used to construct the myofibrils, which are a part of the skeletal muscles of animals. They use the sliding filament model to carry out the muscle contraction and relaxation.
To create movement, The cross-bridge between actin and the myosin heads causes the sacromere to shorten. Muscle fibers contract as a result of this shortening of the sacromere, which has the overall effect of shortening the fibers.

D. they are homologous
homologous is when the organs/limbs etc are similar in position and structure but the function doesn’t have to be the same
This is rly not my level but i take honor classes so i’m above average, i think the answer is D. it’s the most logical to me if you rly want to know
Photosynthesis is a two stage process in which the first stage is light dependent and occurs in the thylakoid membranes where photosynthesis exist. The products of the first stage are needed for the second stage to occur in the stroma of the chloroplasts.
