Which explains how the moon and, to some degree, the sun cause tides on the earth?

a. the moon and sun exert a gravitational pull on the earth. the sun pulls strongest on the ocean water on the same side, while the moon pulls on the ocean water on the side opposite the moon. the pull creates tidal bulges that are earth’s high tides. low tides occur at the halfway point between the bulges.

b. the moon and sun exert a gravitational pull on the earth. the moon pulls strongest on the ocean water on the same side, lesser on the solid earth, and the least on ocean water on the opposite side of the earth. the pull creates tidal bulges that are earth’s high tides. low tides occur at the halfway point between the bulges.
