Answer 1

The correct option is A

Explanation:

1. A pulse is a single disturbance that propagates through a transmission medium.
2. A pulse will reflect off a free end and back with the identical direction of displacement that it had before reflection.
3. A disturbance, which is sudden and lasts for a short duration of time is called a pulse.

Hence, option (a) is correct.
