obviously rock properties.because if the rock proves to be igneous rock,then the mountain is formed from lava deposition,in this case the rock will prove to be a sedimentary mountain,because the continents are on plates,according to plate techtonic theory,earlier there was a plane named gondonaland before it become the highest mountain the everest.when two plates slightly displaced the sedimentation of earth get pressurised in betwwen the two plates,and formed the mountain.so option d is correct.
