Identify the incorrect match between crop, variety and its resistance to insect pest

Crop	Variety	Insect pest
a. Rapeseed mustard	Pusa Sawani	Shoot and fruit borer
b. Flat bean	Pusa Sem 2, Pusa Sem 3	Jassids, aphids, and fruit borer
c. Okra	Pusa Gaurav	Aphids

The correct option is C a and c
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. Aphids 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.
