Answer 1

Answer: (B)

Increase in height

The most conspicuous (clearly visible) change during puberty is the sudden increase in height. During puberty, the long bones or the bones of the arms and legs elongate and make a person tall. It mainly takes place in the presence of male hormone known as testosterone which is responsible for secondary sexual characters.

So, the correct answer is option B.
