Displacement X= r cos(θ)
Diff. It.
Velocity V= r (- sin(θ)).
V= r cos(90+θ).
So that, Velocity leads by 90 °.

x = rcoswt and therefore,
v = -rwcoswt = rwcos(90+wt)
It means clearly, velocity vector leafy by 90° to displacement vector.
v = -rwcoswt = rwcos(90+wt)
It means clearly, velocity vector leafy by 90° to displacement vector.

No, displacement is cosine and velocity is sine fn.

Yes, right @Chahat.
But the displacement is sinu fn & velocity is cosine fn if you said sinusoidal leads cosine fn by 90. Then displacement leads velocity by 90. Then the answer is correct for that velocity legs displacement by 90.
Correct me if I am wrong.

Leads is correct as,
Displacement curve is cos fn.
And velocity fn is sinusoidal.
And sinusoidal leads cos function by 90°
Displacement curve is cos fn.
And velocity fn is sinusoidal.
And sinusoidal leads cos function by 90°
