The correct option is C angular momentum 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, here we can see that both the Planck's constant and Angular momentum have the same dimensions.
