Question

Quizplus · Accepted Answer

Water ice is most prominently found underneath the northern polar cap on present-day Mars, as confirmed by various missions and observations. While there may be water molecules scattered throughout the surface rocks, it is not present in a significant quantity to be considered as predominantly found. Similarly, while there may be water ice underneath both polar caps, it is more prominently and abundantly found underneath the northern polar cap. Therefore, option B is the best choice. Option D is incorrect as Mars still has water in the form of ice and even liquid in some areas.
