When is the turning effect of a force on a door greater?

When turning a door the turning effect of a force on a door is greater at a point far away from the hinges and perpendicular to the door. The turning effect of a pivot is known as the moment about that point. The moment of a force is a measure of its turning effect.

Moment = force * perpendicular distance from the line of action of the force.

The hinge end cannot move, if you apply force at the hinge, it won’t rotate because all of that force will be opposed by the wall to prevent the hinge from moving. However, as the applied force begins to move away from the hinge the turning effect of force is greater and movement is likely to occur.
Therefore other options (A, B and D) are wrong.
