Answer is Right!
Answer is Wrong!
The correct answer is (a) IR-8.
IR-8 is a semi-dwarf rice variety developed by the International Rice Research Institute (IRRI) in the Philippines. It was released in 1966 and was the first high-yielding rice variety to be widely adopted by farmers in India. IR-8 was a major breakthrough in the Green Revolution, which helped to increase food production in India and other developing countries.
Jaya and Ratna are also high-yielding rice varieties that were developed in India. However, they were not as successful as IR-8. Padma is a traditional rice variety that is still grown in some parts of India, but it is not as high-yielding as IR-8.
