Assertion (A): One of the examples of an albuminous seed is Maize.
Reason (B): Endosperm gets completely consumed in the maize seed.

Options

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

Explanation

To solve the assertion and reason question, we need to analyze both the assertion (A) and the reason (B) provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "One of the examples of an albuminous seed is Maize."
- Albuminous seeds are those that retain their endosperm during seed development. In these seeds, the endosperm remains present and is not fully consumed by the developing embryo.

2. **Understanding the Reason (B)**:
- The reason states that "Endosperm gets completely consumed in the maize seed."
- This statement implies that in maize seeds, the endosperm is entirely utilized during the development of the embryo.

3. **Evaluating the Assertion**:
- Maize is indeed classified as an albuminous seed. This means it retains its endosperm, which is a characteristic of albuminous seeds.

4. **Evaluating the Reason**:
- The reason provided is incorrect. In maize, the endosperm is not completely consumed; it remains present in the seed after the embryo has developed.

5. **Conclusion**:
- Since the assertion (A) is true and the reason (B) is false, we can conclude that the correct relationship is that the assertion is correct, but the reason is incorrect.

### Final Answer:
- The assertion is true, and the reason is false. Therefore, the correct option is that the assertion is true, and the reason is false.
