Answer 1

Right option is (a) Surface and Subsurface drip irrigation

Easy explanation: Surface drip irrigation and subsurface drip irrigation are the two main types of drip irrigation. In surface drip irrigation the water is delivered to the surface of the soil directly above the root system of the plants. In subsurface drip irrigation the water is applied directly to the root system.
