B. That the gravitational mass and inertial mass are equal in an experimental result.
C. That the acceleration due to gravity on earth is the same for all bodies is due to the equality of gravitational mass and inertial mass.
D. gravitational mass of a particle like proton can depend on the presence of neighbouring heavy objects but the inertial mass cannot.
