B. A muscle at rest, muscle work by contracting, stage 2 is at work

Answer:

The correct would be option b.

It can be explained with the help of the H zone.

H zone is the region of the muscle which consists of only the thick filament, that is, myosin.

In a relaxed state, the thickness of the H zone is more as compared to the contracted state.

In the contracted state, the myosin pulled the actin fibers towards the M line due to which thickness of H zone decreases.
