Can someone help me :(

Betty is sitting on of her surfboard out in the ocean. She is waiting for the perfect wave to come along so she can ride it in to shore. As she waits, she notices that the waves roll by in patterns, or sets.

. Betty sees a large speed boat pass in the distance. The boat’s motion causes small waves to form and travel outward. What will most likely happen as the larger ocean waves approach the waves created by the boat?
A. The waves will meet and then move in opposite directions.
B. The waves will cancel each other out and make the water flat.
C. The waves will combine and continue moving in the direction of the larger wave.
D. The waves will momentarily create a new wave with a crest higher than the original wave.
