    "The gravitational potential (V) is the gravitational potential energy (U) per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity." from the pedia of wiki

    so the units of gravitational potential are J/kg or nm/kg

    the units of any force are newtons

    so c) makes no sense at all
