a. using more water
b. using less water
c. using cleaner water
d. using dirty water

please select the best answer from the choices provided

a
b
c
d

Explanation:

Efficient plumbing aims to minimize water usage. Using less water means less wastewater is generated, which in turn reduces the amount of water that could potentially be polluted or needs treatment. Option a (using more water) would increase water usage and likely pollution. Option c (using cleaner water) doesn't directly relate to reducing pollution through plumbing efficiency. Option d (using dirty water) is not a function of efficient plumbing and would not reduce pollution. So the correct answer is b.

Answer:

b. using less water
