Answer 1

Correct, C is the correct answer. The presence of marine fossils in the sedimentary rocks found high in the Himalayan Mountains suggests that the Earth's crust that formed the mountains was once covered by an ocean. This supports the idea of plate tectonics, with the Indian subcontinent plate slowly pushing against the Eurasian plate to create the Himalayas.
