A. Pulley system
B. Drip system
C. Sprinkler system
D. Lever system

Answer 1

Hint: Irrigation is the process by which water is supplied to plants at regular intervals. Irrigation is very helpful in areas which have dry soil and less rainfall. It also has important roles in agricultural crop production, maintenance of landscapes, and re-growth of vegetation.

Complete Answer:
- Irrigation can be done by different systems which are stated in the question. The pulley system of irrigation water is drawn manually from the wells with the help of a pulley system. It is then directly applied to the fields.
- Drip system of irrigation is a micro irrigation type where water drips slowly, drop by drop fashion to the roots of the plants. This minimizes evaporation of water as water is placed very closely to the root zone from where they are taken up.
- Sprinkler system involves applying water in a manner similar to that of rainfall. They can also be used for cooling purposes or to reduce airborne dust. Lever system of irrigation is also a traditional method of irrigation where a wheel is attached to a pulley and this helps to pull water out of wells which are then applied to fields.

So the correct option is B) Drip system.

Note: Irrigation of water is a very important process that is widely used for the growth of economically important crops. Nowadays the newer systems like drip and sprinkler have taken over the traditional methods because they have added advantages.
