A. Inertial mass is a measureof difficulty of accelerating a body by an external forcewheeas the gravitational mass is relevant in determining the gravitational force on it by an external mass.
B. That the gravitational massand inertial mass are equal in an experimental result.
C. That the acceleration due to gravity on earth is the same for all bdies is due to the equality of gravitational mass and inertial mass
D. Gravitational mass of a particle like proto can depend on the resence of neghbouring heavy objects but the inertial mass cannot.
