Which set is similar : -
A
Corpus luteum – Graafian follicles
B
Sebum – sweat
C
Bundle of His – Pacemaker
D
Vitamin $B_7$ – Niacin
Detailed Solution
After ovulation, the ruptured Graafian follicle is transformed into the corpus luteum, which secretes progesterone. So the corpus luteum and the Graafian follicle are structurally related (one develops from the other).
Sebum (oily secretion of sebaceous glands) and sweat (watery secretion of sweat glands) are different secretions.
The bundle of His conducts the impulse, while the pacemaker (SA node) starts it.
Vitamin $B_7$ is biotin, while niacin is vitamin $B_3$.
So the similar set is corpus luteum – Graafian follicles.
