It's the Earth.
The question seems poorly worded, but Earth is the planet with liquid water on its surface.

Earth is the only one I know of.
Only earth.
Earth is the only planet known to have liquid water oceans on its surface.
No, there is not enough water on Earth to cover the entire planet. The Earth's surface is about 70 water, but most of it is in the oceans, which only cover about 71 of the planet's surface.
Definitely. Out of every planet in our Solar System, Earth is the only one with liquid water on its surface.
The only planet known to have liquid (flowing) water is Earth. However, Mars and possibly the moon have frozen ice caps at their north and south poles.
Only one planet, Earth, has flowing liquid water. However, liquid water may exist on Jupiter's moon Europa, under a thick outer surface of ice (up to 10 km thick). It is possible, though unconfirmed, that heat is formed from tidal friction with Jupiter's gravity, and at least some of the water is liquid.
Earth. That's only on the surface of course.
The Earth is sometimes called the "Blue Planet" or "Water Planet" because it is the only known planet that has large amounts of liquid water. Water bridges the gap to life, so water makes it possible for the Earth to support life.
The Earth's total surface is 80% water and only 2.5% is fresh water.
