D. The liquid surfac water must have been present in the ancient times
Mostly, the mineral named as Jarosite is found on mars surface. It is a mineral having acidic characteristics with sulfur-rich environments (Baron and Palmer, 1996).
Several groups of Sulfates, including jarosite on Mars are mainly interpreted as evidence of surface and near-surface waters present at the time of their formation.
