Which of the following is mismatched ?

Options

A. Anther-produces microsporangia
B. Pistil-produces pollen
C. Ovule becomes seed
D. Ovary—becomes fruit

Explanation

To solve the question "Which of the following is mismatched?" we will analyze each option provided:

1. **Option A: Anthra produces microsporangia.**
- The anther is indeed responsible for producing microsporangia, which are the structures that give rise to pollen grains. This statement is correct.

2. **Option B: Pistil produces pollen.**
- The pistil is the female reproductive part of the flower, which consists of the stigma, style, and ovary. It does not produce pollen; pollen is produced by the anther (part of the stamen, which is the male reproductive part). Therefore, this statement is incorrect and is the mismatched pair.

3. **Option C: Ovule becomes seed.**
- After fertilization, ovules develop into seeds. This statement is correct.

4. **Option D: Ovary becomes fruit.**
- After fertilization, the ovary develops into a fruit. This statement is also correct.

Based on the analysis, the mismatched option is **B: Pistil produces pollen.**

### Step-by-Step Solution:
1. **Identify the parts of the flower:**
- Understand the roles of the anther (produces pollen) and the pistil (female part).

2. **Evaluate each option:**
- Option A is correct.
- Option B is incorrect (mismatched).
- Option C is correct.
- Option D is correct.

3. **Conclude the mismatched pair:**
- The mismatched pair is Option B.
