The adolescent male consists of enlarge nose as well as the thyroid cartilage. These fuse together to form the large component of the larynx. This anterior larynx is also known as Adam's apple in case of males develop at the time of puberty.

Thus, the correct answer is option (D).

Answer 2

The correct answer is D. Nose and thyroid cartilages.

Step-by-step explanation:

During puberty, many changes occur in the body of both males and females due to the change in hormonal balance and secretion. During adolescence, the male height is increased abruptly and their body starts becoming muscular.

In males during the puberty days, nose and thyroid cartilage enlarges disproportionately. The reason for disproportionate nose in males is that male requires more oxygen for muscles than females. In males, the thyroid cartilages enlarge more than females and responsible for vocalization in them. So the correct answer is D.
