Pick up the correct statement from the following:

• The units of moment of inertia of a plane area, depends upon the units of the area and the length
• The moment of inertia is expressed in m4 if the area is in square metres and the length is also in metres
• The moment of inertia is expressed in cm4 if the area is in square centimetres and the length in centimetres
• The moment of inertia is expressed in mm4 if the area is in square millimetres and the length in millimetres
• All the above.
