Explanation:
The South American and African plates moved apart as a divergent boundary formed between them and an ocean basin formed and spread. At divergent plate boundaries, rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.

The correct answer is that the H zone becomes narrower.
The H-band refers to the region of the thick filaments, which is not overlaid by the actin (thin filaments). Within the H-zone is a thin M-line, which is formed of cross-connecting components of the cytoskeleton.
At the time of muscle contraction, the A-bands do not vary in their length, whereas the H-zone and the I-bands shorten. This makes the Z-lines come near to each other.
