The correct answer is (a) Punjab.
Punjab is the state with the highest productivity of rice in India. In 2020-21, the state produced 17.5 million tonnes of rice, which was 25% of the total production of rice in India. The productivity of rice in Punjab is 6.5 tonnes per hectare, which is much higher than the national average of 4.2 tonnes per hectare.
The high productivity of rice in Punjab is due to a number of factors, including:
- The use of high-yielding varieties of rice
- The use of modern agricultural practices
- The availability of irrigation water
- The availability of skilled labor
- The favorable climate
Punjab is a major producer of rice in India. The state has a long history of rice cultivation and has developed a number of technologies to improve the productivity of rice. The state government has also implemented a number of policies to promote rice cultivation. As a result, Punjab has become one of the most important rice-producing states in India.
The other options are incorrect because they do not have the highest productivity of rice. Uttar Pradesh is the second largest producer of rice in India, but its productivity is lower than that of Punjab. Haryana is the third largest producer of rice in India, but its productivity is even lower than that of Uttar Pradesh. None of the above is also incorrect because it does not specify any state.
