The right option is; D. ice caps of Antarctica

Up to 70% of the world’s freshwater can be found in the ice caps of Antarctica.

The ice sheet of Antarctic is the biggest single mass of ice on the earth surface. It is composed of 30 million cubic km of ice and it extends over an area of almost 14 million square km. The ice cap of Antarctic holds about 70 percent of the fresh water on the earth's surface. Through frost and snow, ice enters the sheet and leaves by melting and breaking of icebergs usually at the bottom.

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
