Find out the correct combinations :-
(a) LH - Development of ovarian follicle.
(b) ACTH - Synthesis of steroid hormone.
(c) Oxytocin - Ejection of milk
(d) FSH - maintenance of corpus luteum.

Options

A. a, b
B. b, d
C. b, c
D. c, d

Answer

To analyze the combinations provided in the question, we will evaluate each hormone and its corresponding function:

### Step-by-Step Solution:

1. **Evaluate LH (Luteinizing Hormone)**:
- LH is primarily responsible for triggering ovulation and the development of the corpus luteum after ovulation.
- The statement claims that LH is responsible for the "development of ovarian follicle," which is incorrect. The development of ovarian follicles is mainly stimulated by FSH (Follicle Stimulating Hormone).
- **Conclusion**: This combination is **incorrect**.

2. **Evaluate ACTH (Adrenocorticotropic Hormone)**:
- ACTH stimulates the adrenal cortex to produce and release steroid hormones, particularly cortisol.
- The statement claims that ACTH is responsible for the "synthesis of steroid hormone," which is somewhat accurate, but it does not specify that it acts on the adrenal cortex.
- However, ACTH is not directly involved in the synthesis of steroid hormones; it stimulates their release.
- **Conclusion**: This combination is **incorrect**.

3. **Evaluate Oxytocin**:
- Oxytocin is known for its role in the ejection of milk during breastfeeding, as well as in uterine contractions during childbirth.
- The statement claims that oxytocin is responsible for the "ejection of milk," which is correct.
- **Conclusion**: This combination is **correct**.

4. **Evaluate FSH (Follicle Stimulating Hormone)**:
- FSH is primarily responsible for the growth and maturation of ovarian follicles.
- The statement claims that FSH is responsible for the "maintenance of corpus luteum," which is incorrect. The maintenance of the corpus luteum is primarily influenced by LH.
- **Conclusion**: This combination is **incorrect**.

### Final Answer:
- The only correct combination from the options provided is:
- (c) Oxytocin - Ejection of milk (Correct)
