Answer 1

The correct option is B polyhouse farming

Polyhouse/greenhouse is a safe house made of transparent material like glass or polyethylene where plants are grown under controlled climatic conditions. The plants receive their nutrients and water through drip irrigation. The polyethylene cover keeps the plants exposed to sunlight and also protects them from pests. Though this practice is expensive to set up, but in the long run they have very high yields and profits.
