Why doesn’t the surface of a wooden boat reflect light as the surface of water does?

• Because the boat's surface is rough and absorbs more light.

• Because the surface of the boat is red, not blue.

• Because the boat is not a natural object like the water is.

• Because the boat is on top of the water's surface.
