It's A. because after the Hebrews had been forced into slavery for many years Moses (a Hebrew baby raised by the Pharaoh's daughter) fled Egypt in fear of his life after killing a taskmaster and later comes back and requests that Pharaoh free the Hebrew people. Pharaoh refused, and Moses brought 10 plagues on Egypt until finally the pharaoh told them to leave and then the Hebrews fled to Canaan. (I suggest you look in the first four books of the Bible for more answers)
