C Correct answer
Explanation

When producing a wave on a spring, the wave velocity is determined by the medium's properties (tension, linear density, stiffness). You can change amplitude (how hard you shake), frequency (how fast you shake), and wavelength (resulting from frequency), but not the velocity itself; it's fixed by the spring.
