The correct answer is Option A) God gave the Ten Commandments to the Prophet Moses on top of Mount Sinai.
The event occured when Moses had freed the Hebrew slaves and was taking them to the 'promised land' i.e. Palestine.
While they were travelling, the group rested near a mountain which is situated in modern-day Egypt, called Mount Sinai.
Moses went up to the mountain for a couple of days and brought back with him the Ten Commandments which every Hebrew/Jew must abide by.
The Ten Commandments are the foundations of religious law in the Judeo-Christian tradition and are a significant event in the Jewish history.
