Answer: a. paddy and millets

Different crops need different requirements and suitable climatic conditions, with the help of which they can flourish in their full glory. 

So, according to these different requirements and climatic conditions, crops that are grown in India, are divided into two categories - 

1. KHARIF CROPS 

Also known as monsoon crops. 

The Kharif cropping season begins with the arrival of the monsoon in the Indian subcontinent.

Kharif crops are traditionally planted at the start of the first monsoon rains. The harvesting season runs from the third week of September to the end of October.

The period of sowing and harvesting depends on the pattern of rainfall from one region in India to the other. 

So, the crops that need a good amount of rain for their growth are grown during the monsoon period and are hence called Kharif crops. 

EXAMPLES - 

Rice (Paddy)

Cotton

Soybean

maize

Millet

2. RABI CROPS 

Rabi crops are classified as winter crops.

They're harvested in October or November. Since they are grown in dry areas, these crops necessitate regular irrigation.

They are sown in winters in harvested in spring.

EXAMPLES -

Wheat

Bajra

Gram

Barley

Mustard
