Best answer
The correct answer is (a) Knapsack type

The explanation is: Knapsack type is a sprayer with the fluid container carried on the back of the operator. It is a compressed air type sprayer which has an air tight chamber. An air pump is mounted on the chamber. The container is filled 3/4^th full so as to leave enough space to compress a good volume of air above the spray material.
