Answer: D
\(\mathrm{ML^2T^{-2}}\) is the dimensional formula of a couple, or torque.
Torque is force times perpendicular distance: \(\mathrm{MLT^{-2}} \times \mathrm{L} = \mathrm{ML^2T^{-2}}\). Work and energy share these dimensions, though torque is a vector and they are scalars. Moment of inertia is \(\mathrm{ML^2}\) and pressure \(\mathrm{ML^{-1}T^{-2}}\).
