Solution
Verified by Toppr

Planck's constant, symbolized h, relates the energy in one quantum (photon) of electromagnetic radiation to the frequency of that radiation.

h=Ev=[ML2T−2][T−1]=[ML2T−1]

Angular momentum = Moment of inertia × Angular velocity (Angular momentum)

=[ML2][T−1]=[ML2T−1]

So, correct answer is option (B).
