Which of the following events is associated with the Ten Plagues of Egypt?

The event associated with the Ten Plagues of Egypt is the water turning to blood. This event is specifically described in the Book of Exodus, where God turned the Nile River into blood as one of the first plagues unleashed upon Egypt. This miracle serves as a demonstration of God's power and serves as a means to compel Pharaoh to release the Israelites from slavery. The plagues are significant components of the Exodus narrative, showcasing the struggle between God's will and Pharaoh's obstinacy.

In contrast, the parting of the Red Sea occurs after the plagues, serving as the climax of the Israelites' departure from Egypt. The Mount Sinai covenant refers to the receiving of the Ten Commandments and other laws after the Israelites have escaped from Egypt. The fall of Jericho is an entirely different event that takes place long after the Exodus and the plagues, related to the conquest of the Promised Land. Thus, water turning to blood is the event that directly connects to the Ten Plagues of Egypt.
