When A and B are two objects with masses $8\mathrm{kg}$ and $38\mathrm{kg}$ respectively, then

Newton's first law of motion: Also known as the law of inertia. The ability of a body to resist change is referred to as inertia.

Unless acted upon by an external force, an object will remain at rest or in uniform motion in a straight line, according to Newton's first law of motion.

The inertia of a body is proportional to its mass.

The greater the mass, the greater the inertia. As a result, object B will have more inertia than object A. As a result, option 2 is correct.
