Options

A. 11 million tones to 75 million tonners
B. 35 million tonnes to 89.5 million tonnes.
C. 350 million tonnes to 899.5 million tonnes.
D. 110 million tonners to 750 million tonnes.

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question asks about the increase in rice production in India from the year 1960 to 2000. To answer this, we need to know the rice production figures for these years.

2. **Historical Background**: After India's independence, rice production was relatively low, making it challenging to feed the growing population. This led to the import of rice from other countries.

3. **Introduction of Dwarf Varieties**: In the 1960s, a significant breakthrough occurred with the discovery of a dwarf gene in Taiwan. This gene was crucial in developing semi-dwarf rice varieties.

4. **Development of Semi-Dwarf Varieties**: The semi-dwarf varieties that emerged from this research included notable names such as Taiwan, Jaya, Ratna, IR8, IR24, and Taichung native variety. These varieties were instrumental in increasing rice yield.

5. **Impact on Rice Production**: The introduction of these semi-dwarf varieties led to a doubling of rice production, contributing to what is known as the Green Revolution in India.

6. **Rice Production Figures**: Specifically, rice production increased from 35 million tonnes in 1960 to 89.5 million tonnes in 2000.

7. **Conclusion**: Therefore, the correct answer to the question is that rice production increased from 35 million tonnes to 89.5 million tonnes during the period from 1960 to 2000.

**Final Answer**: Rice production increased from 35 million tonnes to 89.5 million tonnes during the period 1960 to 2000.
