Match List-I with List-II.
| List-I | List-II | ||
|---|---|---|---|
| A. | Progesterone | I. | Pars intermedia |
| B. | Relaxin | II. | Ovary |
| C. | Melanocyte stimulating hormone | III. | Adrenal Medulla |
| D. | Catecholamines | IV. | Corpus luteum |
Choose the correct answer from the options given below :
A-IV, B-II, C-III, D-I
A-II, B-IV, C-I, D-III
A-III, B-II, C-IV, D-I
A-IV, B-II, C-I, D-III
A-IV, B-II, C-I, D-III
To match each hormone in List‑I with the structure that primarily secretes it, we consider the well‑known source of each hormone:
1. Progesterone – This steroid hormone is produced in large amounts by the corpus luteum after ovulation. Therefore, Progesterone corresponds to option IV.
2. Relaxin – Relaxin is secreted by the ovary (especially by the corpus luteum and placental tissues) during pregnancy. Hence, Relaxin matches option II.
3. Melanocyte‑stimulating hormone (MSH) – MSH is synthesized in the pars intermedia of the pituitary gland. This gives the pair MSH – pars intermedia, i.e., option I.
4. Catecholamines – The catecholamines (epinephrine, norepinephrine) are produced by the adrenal medulla. Thus, catecholamines correspond to option III.
Putting the matches together gives the final pairing:
A‑IV, B‑II, C‑I, D‑III.
