I believe the answer you're looking for is B. It's Polluted. I hope this helps.

These are the correct answers you guys can definitely trust me on:

#1. It is frozen, when we need it, people with cut it out

#2. The deepest part of the ocean in the Mariana's Trench

#3. Gravity: Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon.
