Answer

To analyze the assertion and reason provided in the question, we will break down each component step by step.

### Step 1: Understand the Assertion
- **Assertion (A)**: "Botanical gardens are ex-situ conservation strategy of plants."
- **Explanation**: Botanical gardens are indeed a form of ex-situ conservation. Ex-situ conservation refers to the preservation of plant species outside their natural habitats. Botanical gardens collect and cultivate various plant species for research, education, and conservation purposes. They serve as living repositories for plant diversity, which can be crucial for species that are endangered or at risk in their natural environments.

### Step 2: Understand the Reason
- **Reason (R)**: "Indian Botanical Garden is situated at Howrah."
- **Explanation**: The Indian Botanical Garden, also known as the Acharya Jagdish Chandra Bose Indian Botanic Garden, is located in Howrah, near Kolkata, India. This statement is factually correct.

### Step 3: Evaluate the Relationship Between Assertion and Reason
- **Independently Correct**: Both the assertion and the reason are true statements.
- **Explanation of Relationship**: However, the reason does not explain why botanical gardens are considered ex-situ conservation strategies. The reason simply states the location of the Indian Botanical Garden, which does not provide an explanation for the assertion regarding the role of botanical gardens in conservation.

### Conclusion
- The assertion is true, and the reason is true, but the reason does not correctly explain the assertion.
- Therefore, the correct conclusion is that both statements are true, but the reason is not the correct explanation for the assertion.

### Final Answer
The correct option is: **Assertion true, Reason true, but Reason is not the correct explanation for Assertion.**
