Solution

The correct option is B Construct septic tanks
Septic tanks are underground tanks in which sewage is collected and allowed to decompose with the use of bacteria. Drainage tanks are used to remove water. Sewage pollutes the water bodies when directly discharged into water bodies like river. Septic canal is a tubular passageway for the disposal for sewage.
Thus, the correct answer is option B.
