Question

in addition to earth, which planet has evidence of water on the surface? mars mercury neptune saturn

Explanation:

Scientific observations and missions (like rovers and orbiters) have found geological features on Mars (such as ancient riverbeds, lakebeds, and recurring slope lineae) that confirm past surface water, and there is evidence of briny water flowing on its surface in modern times. Mercury, Neptune, and Saturn have no confirmed evidence of surface water; Mercury is too hot and has no atmosphere to retain liquid water, while Neptune and Saturn are gas giants with no solid surface for water to exist on.

Answer:

A. Mars
