A. The large pulse continues unchanged, moving to the right.

B. The large pulse continues moving to the right but is smaller in amplitude.

C. The small pulse is reflected and moves off to the right with its original amplitude.

D. The small pulse is reflected and moves off to the right with a smaller amplitude.

E. The two pulses combine into a single pulse moving to the right.
