Assertion (A): India does not export natural rubber. Reason (R): About 97% of India's demand for natural rubber is met from domestic production.

1. Assertion (A): Whether India exports natural rubber varies depending on production levels, domestic demand, and international prices. While India is a major producer, it is also a major consumer. In some years, India might export small quantities, while in others, it might be a net importer. Stating India does *not* export at all might be too strong, but significant, consistent exports are not the norm. Let's consider this potentially true in the context of being a net importer usually. 2. Reason (R): India's domestic production of natural rubber typically meets a large portion of its demand, often around 90% or more in the early 2000s, but usually not as high as 97% consistently. There is usually a gap requiring imports. So, stating 97% is met domestically might be an exaggeration but reflects the high degree of self-sufficiency. Let's consider this broadly true. 3. If domestic production meets almost all demand (R is true), it would explain why exports are limited or non-existent (A is true). 4. The provided answer key is 'D' (A is false but R is true). This means the examiner considered the statement 'India does not export natural rubber' (A) to be false (implying India does export some amount) and the statement 'About 97% of India's demand... is met from domestic production' (R) to be true. 5. Therefore, accepting the key 'D', Assertion (A) is false and Reason (R) is true.
