Options

A. Longitudinal division
B. Equal transverse division
C. Unequal transverse division
D. Oblique division.

Answer

To solve the question regarding the type of division the zygote of Capsella bursa-pastoris undergoes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Recognize that Capsella bursa-pastoris is commonly known as shepherd's purse. This plant is known for its unique fruit shape.

3. **Review Division Types**: The question provides four options for the type of division:
- Longitudinal division
- Equal transverse division
- Unequal transverse division
- Oblique division

4. **Research Zygote Division in Capsella**: In the case of Capsella bursa-pastoris, it is known that the zygote undergoes a specific type of division.

5. **Determine the Correct Division**: Based on botanical studies, the zygote of Capsella bursa-pastoris undergoes **unequal transverse division**. This means that the division does not split the zygote into two equal halves, but rather into two unequal parts.

6. **Select the Correct Option**: From the options given, the correct answer is **unequal transverse division** (Option C).

### Final Answer:
The zygote of Capsella bursa-pastoris undergoes **unequal transverse division**.
