Answer

Brief Explanations:

According to Newton's second - law $F = ma$ (where $F$ is force, $m$ is mass, and $a$ is acceleration), when the force (engine force is constant here) is fixed, acceleration $a=\frac{F}{m}$. So, decreasing the mass $m$ will increase the acceleration $a$. Increasing inertia (which is related to mass) would decrease acceleration. Decreasing reaction force or increasing action force is not applicable as the engine force is the same.

Answer:

decreasing the mass of the car
