Hint: The 4Rs in the 4R concept signifies Recycling, Renovation, Recharge and Reuse. The main aim of the 4R concept will give us an idea about what is pollution; this concept is based on.

Complete step-by-step answer:
Recycling, Renovation, Recharge and Reuse is a 4R based concept of waste water.
The waste water consisting of domestic sewage, industrial effluents, thermal and radioactive pollutants receive some sort of treatment before mixing into water bodies., urban edge and sludge etc . It may be recycled and reused to generate cheaper fuel gas and electricity.
Therefore we can say that the 4R concept is a measure to control water pollution. So the correct option is Option C.

The 4R concept is a backbone of solid waste management in a town.
By reducing, we mean to limit the amount of waste we create in the first place. This includes buying products with less packaging.
By reusing, we mean something again that we would normally throwaway for example glass jars for food or plastic bags for bin liners.
By recycling we mean the product going through a mechanical process to change its form. This is only recommended when reducing and reusing and not possible.
By recovering we mean to convert waste into resources such as electricity, heat, compost and fuel through thermal and biological means. Resource recovery occurs after reduction, reuse and recycling have been attempted.

Note: The 4R concept that is mentioned in the answer represents an order. The order should be followed by every organization, as well as the government to reduce water pollution. The implementation also prevents the wastage of materials which can be better utilized, for the betterment of mankind.
