A increased level of inhibin

B Decreased level of follistatin

C decreased level of activin

D None of above

Ans. B

Decreased level of follistatin

“activin stimulates FSH secretion and inhibin inhibits it."

b. Hence, it is the decreased level of activin which causes increased level of follistatin and thus delays puberty.
