D. 2

Answer

To solve the question of how many pollen sacs are present in a mature anther, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Anther**:
- The anther is a part of the stamen, which is the male reproductive organ of a flower. It is typically located at the top of the filament.

2. **Identify the Lobes of the Anther**:
- A typical anther is bilobed, meaning it has two lobes. However, some anthers may have only one lobe.

3. **Determine the Number of Pollen Sacs**:
- Each lobe of a bilobed anther contains two pollen sacs, also known as thecae.

4. **Calculate the Total Number of Pollen Sacs**:
- Since there are two lobes and each lobe has two pollen sacs, the total number of pollen sacs in a bilobed anther is:
\[ 2 \text{ (lobes)} \times 2 \text{ (pollen sacs per lobe)} = 4 \text{ pollen sacs} \]

5. **Conclusion**:
- Therefore, a mature anther typically has **4 pollen sacs**.

### Final Answer:
The correct answer is **4**.
