The slopes of active Martian volcanoes appear to have been covered with ice and debris flows, and the mineral jarosite, which is considered to have developed in the presence of water, is found in Martian rocks. This undiscovered evidence suggests that there was once liquid water on Mars. Here, choices B and D are the right ones.
On Mars, meanders do exist, but they are not the result of water. Lava-like volcanic flows were what gave rise to it. Researchers came to the conclusion that water was really a significant component in the development of this mineral from the minerals they had isolated from the salt deposits that were present. It's called jarosite.
Additionally, the radar picture demonstrates that ice and debris are in fact extant and were formerly a component of large glaciers. The most important example is this one since radars can readily pick it up. Therefore, the finest instances of this identification of water on Mars are the glaciers and the minerals.
