D. Until now, more than 90 biosphere reserves have been established.

Answer

To solve the question, we need to analyze each statement provided and determine which one is correct.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The statement claims that "Aravalli hills in Rajasthan are sacred grooves."
- Sacred grooves are areas that are preserved for their religious significance and biodiversity. The Aravalli hills do have sacred groves, making this statement correct.

2. **Analyze the Second Statement:**
- The statement claims that "zoological parks are in in-situ modes of conservation."
- In-situ conservation refers to conserving species in their natural habitats. Zoological parks, however, are examples of ex-situ conservation, where species are kept in artificial habitats. Thus, this statement is incorrect.

3. **Analyze the Third Statement:**
- The statement claims that "in India, 34 hotspots are found."
- This is incorrect because there are 34 biodiversity hotspots recognized globally, not specifically in India.

4. **Analyze the Fourth Statement:**
- The statement claims that "more than 90 biosphere reserves have been established in India."
- This is also incorrect. As of now, there are 18 biosphere reserves established in India.

5. **Conclusion:**
- After analyzing all statements, we find that the first statement is the only correct one.

### Final Answer:
The correct statement is: **"Aravalli hills in Rajasthan are sacred grooves."**
