The correct answer is (a) April – May.
Amon rice is a type of rice that is grown in the rainy season in tropical and subtropical regions. It is a short-duration rice variety that matures in about 100 days. Amon rice is grown in many countries, including India, Bangladesh, Pakistan, and Sri Lanka. It is a popular type of rice because it is relatively easy to grow and it is a good source of carbohydrates.
The other options are incorrect because they are not the months during which Amon rice is grown. June – July is the monsoon season in many tropical and subtropical regions, and rice is not grown during this time because the fields are too wet. November – December is the winter season in many tropical and subtropical regions, and rice is not grown during this time because the weather is too cold. May – June is the beginning of the rainy season in many tropical and subtropical regions, and this is the time when Amon rice is grown.
