The correct answer is:
**A. resonance.**
Resonance occurs when an object is made to oscillate at its natural frequency by an external force, leading to an increase in amplitude of the oscillations. In this case, the girl on the swing moving her legs at the natural frequency of the swing exemplifies this phenomenon.
