Options

A. A - (iv), B - (ii), C - (iii), D - (i)
B. A - (ii), B - (iv), C - (i), D - (iii)
C. A - (iv), B - (ii), C - (i), D - (iii)
D. A - (ii), B - (iv), C - (iii), D - (i)

Answer

To solve the question of matching the endocrine glands with their respective hormones, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Identify the Gland and Hormone for Pineal Gland:**
- The pineal gland secretes **melatonin**, which is responsible for regulating sleep patterns.
- Therefore, the match is: **Pineal → Melatonin** (Option B).

2. **Identify the Gland and Hormone for Thyroid Gland:**
- The thyroid gland produces hormones that regulate metabolism, primarily **triiodothyronine (T3)** and **tetraiodothyronine (T4)**.
- The specific hormone we are focusing on here is **Tetraiodothyronine (T4)**.
- Therefore, the match is: **Thyroid → Tetraiodothyronine** (Option D).

3. **Identify the Gland and Hormone for Ovary:**
- The ovaries produce hormones such as **estrogen** and **progesterone**.
- Here, we are focusing on **estrogen**.
- Therefore, the match is: **Ovary → Estrogen** (Option C).

4. **Identify the Gland and Hormone for Adrenal Medulla:**
- The adrenal medulla secretes **epinephrine (adrenaline)**, which is involved in the fight-or-flight response.
- Therefore, the match is: **Adrenal Medulla → Epinephrine** (Option A).

### Summary of Matches:
- A. Pineal → (ii) Melatonin
- B. Thyroid → (iv) Tetraiodothyronine
- C. Ovary → (iii) Estrogen
- D. Adrenal Medulla → (i) Epinephrine

### Final Answer:
The correct matches are:
- A → (ii)
- B → (iv)
- C → (iii)
- D → (i)

Thus, the correct option that matches all glands with their hormones is **Option 4**.
