Answer 1

Liquid water may have existed on Mars in the past, and the presence of water is still possible.

Step-by-step explanation:

The most true statement regarding the presence of water on Mars is option 2) There is evidence that suggests that liquid water may have existed on Mars, and the presence of water is still a possibility. Although liquid water is not stable on the surface of Mars today due to low temperatures and pressures, there is evidence of flowing water in the past and the presence of water in the form of ice beneath the surface.
