The correct answer describes Newton's second law of motion : A. Force = mass x acceleration (F=m.a)
Further explanation
Newton's 2nd law states that :
the acceleration from the applied force is proportional to the resultant force and inversely proportional to the mass
Can be formulated
![\tt a=(F)/(m)](https://img.qammunity.org/2021/formulas/chemistry/high-school/5tg3k71d9cue724y5qceh91lchq1krkmar.png)
or
![\tt F=m* a](https://img.qammunity.org/2021/formulas/chemistry/high-school/4qb8gdagb0gdh1v7wyqq7gki8ujahgt337.png)
F = force, N
m = mass, kg
a = acceleration, m/s²
