The mass of a body:

The quality of a body's substance, or mass, is independent of its position, acceleration, and rate of free fall.

We must respond to what factors determine a body's bulk.
We now understand that a body's mass determines its inertia or resistance to change of motion. We may state that mass is a characteristic of the physical body as well as an indicator of how resistant it is to acceleration when a force is applied.
Now, we may argue that a body's mass is the nature of its substance and that it is unrelated to its location, acceleration, or rate of free fall. As far as we are aware, our body's mass remains constant wherever we travel.

Any body's mass is determined by $m=\rho \times v$, where $\rho$, where v is the volume and is the body's density.

Therefore, we are aware that if density varies, mass for a given volume will also vary.
Since spring balance assesses a body's weight, which varies depending on where on the body it is placed, it cannot be quantified.
Therefore, if we consider the above option, option B may be the greatest choice because a body's mass is independent of the acceleration of free fall.
Additionally, the remaining choices are incorrect since the mass is constant throughout the whole planet. Additionally, if the density varies, the mass of all bodies with the same volume will not be the same. Additionally, the last choice is incorrect since the spring scale measures weight rather than mass.

Hence, the correct answer is option B.
