Solution

The correct option is A cannot be determined
The variable $ω$ used in SHM is angular frequency and not angular velocity. Angular velocity refers to a particle executing circular motion, while in SHM, we are approximating a curved path into a straight line
Thus, we only determine the number of oscillations per sec and multiply this by $2 π$ to express the same as the angular frequency in terms of rad/s
The correct option is (d)
