The gravitational force is doubled.

The gravitational force is halved.

The gravitational force remains the same.

The gravitational force is quadrupled.

Inertial mass measures an object's resistance to acceleration, while gravitational mass measures how strongly an object interacts with gravity.

Inertial mass measures how strongly an object interacts with gravity, while gravitational mass measures an object's resistance to acceleration.

Inertial mass is measured in kilograms, while gravitational mass is measured in Newtons.

Inertial mass and gravitational mass are completely unrelated concepts.
