Two symmetrical pulses move towards each other along the same side of a stretched spring. As the pulses meet and overlap, what is the likely outcome?

A. Constructive interference, resulting in a pulse with greater amplitude.
B. Destructive interference, canceling out the pulses and creating a momentary flat section.
C. Reflection, causing the pulses to bounce back along the spring.
D. Diffraction, leading to the spreading of the pulses in multiple directions.
