Study the given table and choose the correct option.

Crop	Variety	Insect pest
A	Pusa Gaurav	Aphids
Flat bean	B	Jassids

The correct option is B A: Brassica, B: Pusa Sem 3
Agricultural pests are organisms that attack agricultural crops and destroy them, leading to huge crop losses. Through various plant breeding programmes, the Indian Agricultural Research Institute (IARI) has developed various pest resistant crop varieties. These varieties can hugely overcome the problem of crop losses due to pest infestation.

Pusa Gaurav is a crop variety of Brassica (rapeseed mustard) which is resistant to aphids. They are small sap-sucking insects which damage the crops.

Pusa Sem 2 and Pusa Sem 3 are crop varieties of flat bean which are resistant to jassids, aphids and fruit borers. Jassids and aphids suck the plant sap to destroy it while fruit borers infest the pod of flat bean making holes in it.

Pusa sawani and Pusa A-4 are pest resistant varieties of okra (Lady's finger). They are resistant to fruit and shoot borers.

Himgiri is a disease resistant variety of wheat developed by the IARI that is resistant to the fungal diseases such as leaf and stripe rust and hill bunt.

Hence, option b is correct.
