Answer 1

Answer: (A), (B), (C)

The correct options are
A Water is not much contaminated.
B Surface water can get polluted by sanitary works.
C Water is not breeding ground for mosquitoes.

Ground water is found beneath Earth's surface in the cracks and spaces in soil, sand and rock. Since this water is present beneath the Earth's surface, it is difficult to withdraw ground water when compared to surface water. But ground water is mostly free from contamination and also it does not become breeding ground for mosquitoes.
