The amount of saltwater on the Earth's surface is vastly larger than the amount of freshwater.

Most of Earth's water is saltwater, found in the oceans. Oceans cover most of the planet’s surface and hold about 97% of all water. Freshwater, by contrast, makes up only about 3% of all water, and much of that is locked in glaciers and underground, with only a small portion available as liquid water in lakes and rivers. That huge difference in amount is why the statement is true. This isn’t unknown or ambiguous data, and there isn’t a substantial amount of freshwater that matches the oceanic volume, so the other options don’t fit.
