Assertion (A). In situ conservation is an ideal conservation strategy for biodiversity.
Reason (R). It maintains recovering populations in the surroundings where they have developed their distinctive properties

Options

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

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "In situ conservation is an ideal conservation strategy for biodiversity."
- In situ conservation refers to the conservation of species in their natural habitats. This includes protecting ecosystems and natural habitats, as well as the maintenance of viable populations of species in their natural surroundings.

2. **Understanding the Reason (R)**:
- The reason states that "It maintains recovering populations in the surroundings where they have developed their distinctive properties."
- This means that in situ conservation allows species to thrive in their natural environment, where they have adapted over time and developed unique characteristics suited to that environment.

3. **Evaluating the Relationship between A and R**:
- The assertion claims that in situ conservation is ideal, which is supported by the reason. The reason explains that by conserving species in their natural habitats, they can maintain their unique adaptations and recover more effectively than if they were removed from their environment (as in ex situ conservation).

4. **Conclusion**:
- Both the assertion and reason are true statements.
- The reason provided is a correct explanation of the assertion, as it highlights the benefits of in situ conservation in preserving biodiversity.

### Final Answer:
Both the assertion (A) and reason (R) are true, and R is the correct explanation of A.
