• D. Harvester should be replaced by seed drill.

Answer 1

The correct option is A Positions of sprinkler system and drip irrigation should be interchanged.

Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. Drip irrigation is defined as any watering system that delivers a slow-moving supply of water at a gradual rate directly to the soil. Drip irrigation, which is also sometimes referred to as micro-irrigation or trickle irrigation, consists of a network of pipes, tubing valves, and emitters.

so the correct option is 'Position of a sprinkler system and drip irrigation should be exchanged'.
