The correct option is (c) (M L^2T^-2)

To elaborate: Energy is also known as work done, for which the formula is the product of force into displacement, i.e. Work = Force (mass x acceleration) X Displacement (in meters). We know that the dimensions for force and displacement are (MLT^-2) and (L) respectively. Therefore, the dimensions for Energy are (M L^2T^-2).
