Assertion : Although geitonogamy is functionally crosspollination involving a pollinating agent, genetically it is similar to autogamy.
Reason : In geitonogamy, pollen grains from the anthers of one flower are transferred to the sigma of another flower borne on the same plant.

Options

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

Explanation

To analyze the assertion and reason provided in the question, we can break it down step by step:

### Step 1: Understand the Terms
- **Geitonogamy**: This is a type of pollination where pollen grains from the anthers of one flower are transferred to the stigma of another flower on the same plant.
- **Autogamy**: This is self-pollination where pollen from the same flower fertilizes the ovule.

### Step 2: Analyze the Assertion
The assertion states that geitonogamy is functionally cross-pollination involving a pollinating agent, but genetically it is similar to autogamy.
- **Functional Cross-Pollination**: Geitonogamy involves a pollinator (like insects or wind) transferring pollen from one flower to another flower on the same plant, which is a characteristic of cross-pollination.
- **Genetically Similar to Autogamy**: Since both flowers are on the same plant, the genetic material is essentially the same, making it similar to self-pollination (autogamy).

### Step 3: Analyze the Reason
The reason states that in geitonogamy, pollen grains from the anthers of one flower are transferred to the stigma of another flower borne on the same plant.
- This statement accurately describes the process of geitonogamy and supports the assertion.

### Step 4: Conclusion
Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, the correct conclusion is that both statements are true, and the reason is the correct explanation of the assertion.

### Final Answer
Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
