Gravitational mass is proportional to gravitational

The correct option is force.

Underlying Concept:
Mass can be defined in two ways based on how it is measured: inertial mass and gravitational mass. Gravitational mass is the measure of the strength of an object's interaction with a gravitational field.

According to Newton's law of universal gravitation, the gravitational force ($F$) experienced by a body of gravitational mass ($m_g$) in a gravitational field of strength or intensity ($g$) is given by the formula:

$F=m_{g}g$

In a given gravitational field where the gravitational field intensity ($g$) is constant, the relation becomes:

$F\propto m_g$

This shows that the gravitational mass of an object is directly proportional to the gravitational force acting on it. Therefore, a body with a larger gravitational mass will experience a proportionally larger gravitational force in a given field.
