The correct match is
I. DCT - Secretion of `H^(+)` and `K^(+)` ions
II. Henle's loop -Reabsorption of glucose, water and `Na^(+)` ions
III. Podocytes - Attached to parietal layer of Bowman's capsule
IV. JGA - Rise in glomerular blood pressure activates it to release renin.

Options

A. III
B. II
C. I
D. IV

Answer

To solve the question regarding the correct match among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Option I: DCT - Secretion of `H^(+)` and `K^(+)` ions**
- The Distal Convoluted Tubule (DCT) is known for its role in the secretion of hydrogen ions (`H^(+)`) and potassium ions (`K^(+)`). This option is **correct**.

2. **Analyze Option II: Henle's loop - Reabsorption of glucose, water, and `Na^(+)` ions**
- The Loop of Henle primarily facilitates the reabsorption of water and sodium ions (`Na^(+)`), but it does not reabsorb glucose. Therefore, this option is **incorrect**.

3. **Analyze Option III: Podocytes - Attached to the parietal layer of Bowman's capsule**
- Podocytes are specialized cells that form the visceral layer of the Bowman's capsule, not the parietal layer. Thus, this option is **incorrect**.

4. **Analyze Option IV: JGA - Rise in glomerular blood pressure activates it to release renin**
- The Juxtaglomerular Apparatus (JGA) responds to a decrease in glomerular blood pressure, not an increase. Therefore, this option is **incorrect**.

### Conclusion:
The only correct match is:
- **I. DCT - Secretion of `H^(+)` and `K^(+)` ions**.

Thus, the correct answer is **Option I**.
