D. 12

Answer

To determine the number of pyramids in the kidney of a man, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Kidney**: The kidney is a vital excretory organ responsible for filtering blood and excreting waste products.

2. **Identify the Functional Units**: The functional units of the kidney are called nephrons. These nephrons are organized in a specific structural arrangement.

3. **Recognize the Renal Pyramids**: Within the kidney, the nephrons are grouped into structures known as renal pyramids. These pyramids have a cone-like shape and are essential for the kidney's function.

4. **Count the Renal Pyramids**: In a human kidney, there are typically around 8 to 10 renal pyramids. This means that the number of pyramids can be approximated to 8.

5. **Select the Correct Option**: Given the options:
- (a) 4
- (b) 6
- (c) 8
- (d) 12

The correct answer is (c) 8, as it falls within the typical range of renal pyramids found in the human kidney.

### Final Answer:
The number of pyramids in the kidney of a man is **8** (Option C).
