A. Frequency.

Moving the end up and down faster increases the number of oscillations per second (frequency). For a rope with fixed tension and linear mass density the wave speed stays essentially the same, so increasing frequency makes the wavelength shorter (λ = v/f). Amplitude only changes if the end is moved with larger displacement, not merely faster.
