The correct option is A Male with some secondary sexual characters of female

Klinefelter syndrome is a genetic disorder that results when a male is born with an extra copy of the X chromosome. (XXY rather than XY)

Boys and men with Klinefelter syndrome typically have small testes that produce a reduced amount of testosterone. The shortage of testosterone can lead to delayed or incomplete puberty, breast enlargement (gynecomastia), and a reduced amount of facial and body hair.

So, the correct answer is 'Male with some secondary sexual characters of female'.
