Assertion (A): Nucleus is not located in the centre of a plant cell unlike an animal cell.
Reason (R ): Plant cells possess chloroplasts that are not present in an animal cell.

Options

A. Both A and R are true and R is the correct explanation for A.
B. Both A and R are true but R is not the correct explanation for A.
C. A is true and R is false.
D. A is false and R is true.

Explanation

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**: The assertion states that the nucleus is not located in the center of a plant cell, unlike in an animal cell. This is true because, in plant cells, the large central vacuole occupies most of the space in the center, pushing the nucleus to the side.

2. **Understanding the Reason (R)**: The reason states that plant cells possess chloroplasts, which are not present in animal cells. This statement is also true, as chloroplasts are responsible for photosynthesis in plants, while animal cells do not have chloroplasts.

3. **Analyzing the Relationship**: While both the assertion and reason are true, the reason does not explain why the nucleus is not in the center of the plant cell. The presence of chloroplasts is unrelated to the positioning of the nucleus.
