How do the shape, path, and speed of ocean waves change when they move towards shallow water?

a) The shape becomes taller and narrower, the path bends towards the shoreline, and the speed decreases.
b) The shape becomes shorter and wider, the path straightens out, and the speed increases.
c) The shape remains unchanged, the path remains straight, and the speed stays constant.
d) The shape becomes irregular, the path becomes unpredictable, and the speed fluctuates.
