Which of the following pairs have same dimensions – (a) Torque and work (b) Angular momentum and work (c) Energy and moment of inertia (d) Light year and wavelengths

a and d

Torque and work both have dimensions equal to $[ML^2T^{-2}]$

Light year and wavelength both have dimensions same as distance = [L]

Dimension of Energy = $[ML^2T^{-2}]$

Dimension of moment of inertia = $[ML^2]$

Dimension of  Angular momentum = $[ML^2T^{-1}]$
