Accepted Answer

A)  while the wave is moving, some water molecules are traveling in closed circles. 
B)  the waves don't move as fast as speeding cannon balls, so the Coriolis effect has no influence on them.

D)  waves curve one way in the southern hemisphere and the other way in the northern hemisphere. Waves only look like they are coming in a straight line from their point of origin. It's all a gigantic optical illusion, actually.
