[A]: Maximum genetic diversity of crop plants is found in areas where agriculture is primi- tive.
[R]: In such primitive areas, human interfer- ence is minimum and maximum flora and fauna survive

Options

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

Answer

To solve the question, we need to analyze the statements given and determine their validity and relationship to each other.

### Step-by-Step Solution:

1. **Understanding Statement [A]:**
- The statement claims that "Maximum genetic diversity of crop plants is found in areas where agriculture is primitive."
- Genetic diversity refers to the variety of genetic characteristics within a species, which is crucial for resilience and adaptability of crops.

2. **Understanding Statement [R]:**
- The reason provided states, "In such primitive areas, human interference is minimum and maximum flora and fauna survive."
- This implies that in areas where agriculture is less developed, there is less human activity that disrupts natural ecosystems, allowing a greater variety of plant and animal life to thrive.

3. **Connecting [A] and [R]:**
- The relationship between [A] and [R] can be established by recognizing that less human interference allows for the preservation of diverse genetic traits in crop plants.
- In primitive agricultural systems, traditional farming practices often maintain a wider range of crop varieties, which contributes to higher genetic diversity.

4. **Evaluating the Truth of Statements:**
- Statement [A] is true because areas with primitive agriculture do indeed show higher genetic diversity due to the preservation of various crop varieties.
- Statement [R] is also true as it correctly explains that minimal human interference leads to a richer biodiversity of flora and fauna.

5. **Conclusion:**
- Both statements are true, and [R] provides a correct explanation for [A]. Therefore, the answer to the question is that both statements are true and [R] correctly explains [A].

### Final Answer:
Both [A] and [R] are true, and [R] is the correct explanation of [A].
