It ensures sustainable use of clean water.  

The correct answer is option A, reduces water pollution by using less water

Explanation:

The efficient plumbing system nowadays not only focuses on efficient plumbing system with high performance but also emphasizes on the water saving. The best feature about an efficient plumbing is that it works on the concept of natural phenomena with least energy input (electricity/mechanical). All the plumbing fixtures and pipelines are designed in a way that they provide sufficient pressure to water to flow and also save the over consumption of water by regulating the volume of flow.
