Assertion : The two cotyledons in seed are embryonic leaves
Reason : The embryo contains radicle and plumule.

Options

A. If both the assertion and reason are true and reason is correct explanation of the assertion .
B. If both the assertion and reason are true but reason is not a correct explanation of the assertion .
C. If the assertion is true but the reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided:

### Step 1: Analyze the Assertion
The assertion states: "The two cotyledons in seed are embryonic leaves."
- Cotyledons are indeed the first leaves that develop from the embryo of a seed. In dicot seeds, there are typically two cotyledons, which serve as the initial source of nutrients for the developing plant. Thus, this assertion is **true**.

### Step 2: Analyze the Reason
The reason states: "The embryo contains radicle and plumule."
- The embryo of a seed does contain both the radicle and the plumule. The radicle is the part of the embryo that develops into the root, while the plumule develops into the shoot system. Therefore, this reason is also **true**.

### Step 3: Determine the Relationship
Now, we need to determine if the reason correctly explains the assertion.
- While both statements are true, the reason does not provide a direct explanation for the assertion. The assertion is about cotyledons being embryonic leaves, while the reason discusses the components of the embryo (radicle and plumule). They are related but do not explain each other.

### Conclusion
Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the answer is:
- **Both the assertion and reason are true, but the reason is not a correct explanation of the assertion.**

### Final Answer
The correct option is: **Option 2**.
