Question

Match List-I with List-II.

List-I (Hormones)	List-II (Role/functions)
(A) LH (B) FSH (C) Oxytocin (D) Progesterone	(I) Causes stronger uterine contractions (II) Essential for maintenance of the endometrium during menstrual cycle (III) Acts on Leydig cells and stimulates synthesis and secretion of androgens (IV) Acts on Sertoli cells and stimulates secretion of some factors which help in spermiogenesis

Choose the correct answer from the options given below:

• A. \(A \to (I),\ B \to (II),\ C \to (III),\ D \to (IV)\)
• B. \(A \to (III),\ B \to (I),\ C \to (II),\ D \to (IV)\)
• C. \(A \to (I),\ B \to (II),\ C \to (IV),\ D \to (III)\)
• D. \(A \to (III),\ B \to (IV),\ C \to (I),\ D \to (II)\)

Hint:

LH:Leydig cells
FSH: Sertoli cells
Oxytocin: Uterine contractions
Progesterone: Maintains endometrium

Answer 1

The Correct Option is D

Step 1: Function of LH
• LH acts on Leydig cells.
• It stimulates synthesis and secretion of androgens. Thus: \[ A\rightarrow(III) \]
Step 2: Function of FSH
• FSH acts on Sertoli cells.
• It stimulates secretion of factors important for spermiogenesis. Thus: \[ B\rightarrow(IV) \]
Step 3: Function of Oxytocin
• Oxytocin stimulates uterine muscle contractions during childbirth. Thus: \[ C\rightarrow(I) \]
Step 4: Function of Progesterone
• Progesterone maintains the endometrium during menstrual cycle and pregnancy. Thus: \[ D\rightarrow(II) \] Therefore, the correct matching is: \[ A\rightarrow(III),\quad B\rightarrow(IV),\quad C\rightarrow(I),\quad D\rightarrow(II) \] Hence: \[ \boxed{\text{(D)}} \]
