Which of the following is an incorrect match?

Options

A. Bowman's capsule-Glomerular filtration
B. DCT-Absorption of glucose
C. Henle's loop -Concentration of glucose
D. PCT-Absorption of `Na^(+)` and `K^(+)` ions

Explanation

To determine which of the following is an incorrect match, we need to analyze each option provided in the question:

1. **Bowman's capsule - Glomerular filtration**:
- The Bowman's capsule is part of the nephron where glomerular filtration occurs. It receives the filtrate from the glomerulus, where blood is filtered. This match is correct.

2. **DCT - Absorption of glucose**:
- The Distal Convoluted Tubule (DCT) is not primarily responsible for glucose absorption. The majority of glucose reabsorption occurs in the Proximal Convoluted Tubule (PCT). Therefore, this match is incorrect.

3. **Henle's loop - Concentration of glucose**:
- The Loop of Henle plays a role in creating a concentration gradient in the medulla of the kidney, which is essential for the concentration of urine. While it does not directly concentrate glucose, it helps in the overall concentration of solutes. This match is correct in the context of urine concentration.

4. **PCT - Absorption of Na+ and K+ ions**:
- The Proximal Convoluted Tubule (PCT) is responsible for the reabsorption of a significant amount of sodium (Na+) and potassium (K+) ions, approximately 70% of these electrolytes are absorbed here. This match is also correct.

Based on the analysis, the incorrect match is:

**DCT - Absorption of glucose**.

### Final Answer:
The incorrect match is **DCT - Absorption of glucose**.
