Answer 2

Answer:

B) A-band length does not get reduced during muscle contraction.

Explanation:

The rest of the options H-zone, I-band, and sarcomere get shortened during the contraction process of the muscle.

a) H-zone is the central region of the A-zone in the muscle unit containing myosin, whose length gets reduced.

b) the A-band does not change remains the same during the contraction process.

c) I-band's length gets reduced also in the contraction process.

d) sarcomere is the functional unit of the muscular system, which also changes its length during contraction.
