Match the columns and choose the correct answer.
(a) Aldosterone (Column I) (i) Zona fasciculata (Column II) (b) DHEA (Column I) (ii) Zona glomerulosa (Column II) (c) Cortisol (Column I) (iii) Zona reticulans (Column II) (d) Adrenaline (Column I) (iv) Adrenal medulla (Column II)

Options

A. a(i), b(ii), c(iii), d(iv)
B. a(ii), b(iii), c(i), d(iv)
C. a(iii), b(ii), c(i), d(iv)
D. a(iii), b(i), c(ii), d(iv)

Answer

To solve the matching question, we need to identify which hormone corresponds to which zone of the adrenal gland. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Hormones and Their Sources

1. **Aldosterone**: This hormone is produced in the adrenal cortex, specifically in the **zona glomerulosa**. Its primary function is to regulate sodium and potassium levels in the blood, which in turn helps control blood pressure and fluid balance.

2. **DHEA (Dehydroepiandrosterone)**: This hormone is also produced in the adrenal cortex, but it is secreted from the **zona reticularis**. DHEA is an androgen precursor and is often referred to as a "super hormone" due to its wide range of effects in the body.

3. **Cortisol**: This hormone is produced in the adrenal cortex as well, specifically in the **zona fasciculata**. Cortisol plays a crucial role in metabolism, immune response regulation, and stress response.

4. **Adrenaline (Epinephrine)**: Unlike the other hormones listed, adrenaline is secreted from the **adrenal medulla**. It is responsible for the body's "fight or flight" response, increasing heart rate and blood pressure during stress.

### Step 2: Match the Hormones with Their Corresponding Zones

Now that we have identified the sources of each hormone, we can match them with the correct zones:

- (a) **Aldosterone** → (ii) **Zona glomerulosa**
- (b) **DHEA** → (iii) **Zona reticularis**
- (c) **Cortisol** → (i) **Zona fasciculata**
- (d) **Adrenaline** → (iv) **Adrenal medulla**

### Final Matches:

- (a) Aldosterone → (ii) Zona glomerulosa
- (b) DHEA → (iii) Zona reticularis
- (c) Cortisol → (i) Zona fasciculata
- (d) Adrenaline → (iv) Adrenal medulla

### Conclusion:

The correct answer is the second option, which matches the hormones with their respective zones correctly.
