The practice in which the plants are grown to extract water from area of shallow water table, through transpiration process is called as:

Correct option is B

Bio drainage is the practice of using deep-rooted plants to extract excess soil water, especially from areas with a shallow water table.
· The process involves the planting of species with extensive root systems that can absorb water from deeper soil layers.
· This method effectively lowers the groundwater level through the plants’ transpiration, thereby reducing soil waterlogging and improving soil aeration.
· This technique is particularly useful in areas prone to waterlogging and salinity issues.
