Velocity Sine Waves

SATPHY-EYYXBE

The black graph pictured below represents the position-time graph for a spring-mass system oscillating with simple harmonic motion.

The colored, dashed graphs represent shapes of possible velocity time graphs for the same motion.

The vertical axis stands for position or velocity, but the scaling does not matter. The time axis is the same for all graphs.

Which colored graph best represents the possible velocity for the mass in this spring-mass system?
