Step-by-step explanation:
Hello,
In this case, the presence of such sedimentary rocks and fossils demonstrate the earlier existence of an ancient ocean that was covering the Himalayan Mountains due to the found ancient marine life which has no other option to live there because no hint of that type of evolution is available nowadays, therefore, the answer is C) the Earth's crust that formed these mountains was once covered with an ocean.
Best regards.
