Some of the crops are grown in the winter season, they are called as the rabi crops. Seeds of these crops are sown in the beginning of the winter season. After maturation of crops, they are harvested at the end of the winter season. For example, gram, pea, wheat etc.

Rice is the most important human food crop in the world as it is directly feeding more people than any other crop. It is also the staple food across Asia, where around half of the world's poorest people live and is becoming increasingly important in Africa and Latin America. Rice has also fed more people over a longer time than has any other crop. It is spectacularly diverse, both in the way it is grown and how it is used by humans. Rice is unique because it can grow in wet environments that other crops cannot survive in. Such, wet environments are abundant across Asia. So, rice is the main crop of Asia. 

Rice is a Kharif crop. It covers one-third of the total cultivated area of India. It provides food to more than half of the Indian population. Rice is produced in almost all states. Top three producer states are West Bengal, Punjab and Uttar Pradesh. Other rice growing states include Tamilnadu, Andhra Pradesh, Jharkhand, Uttarakhand, Chhattisgarh, Odisha, Uttar Pradesh, Bihar, Karnataka, Assam and Maharashtra. It is also grown in Haryana, Madhya Pradesh, Kerala, Gujarat and Kashmir valley. So, it is the principle cereal crop in India compared to wheat, maize and sorghum. Thus, option B is correct.

The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. As staple foods, cereal grains provide a good amount of carbohydrate, dietary fibre, and protein.

Apiculture deals with the rearing of honeybees.

Any crop that can be grown between October and March or during winter seasons are called as Rabi crop such as wheat, cotton, maize etc., as they do not require more water to grow. Whereas crops that grow during the rainy season are called as Kharif crop such as paddy as they require more water to grow. Thus, the correct answer option A.

Dryland farmed crops may include winter wheat, corn, beans, sunflowers or even watermelon. 

So, the correct option is 'A - 3, B - 1, C - 2, D - 4'
