Answers & Comments
Answer:
The correct option is B
Drip System
Drip irrigation is a technique in which water flows through a filter into special drip pipes. It helps in releasing water drop by drop into the soil near the roots of plants. In contrast to other types of irrigation systems such as overhead sprinklers, water can be more precisely applied to the plant roots. If designed, installed and managed properly, this method contributes greatly to water conservation by reducing evaporation and deep drainage.
