Acceleration can be defined as the rate of change in the velocity of an object. Option C is correct.
[tex]a = \dfrac {v-u}t\ \ \ \ \rmor}\\\\a = \dfrac {\Delta v }t[/tex]
Where,
[tex]a[/tex] - acceleration
[tex]\Delta v[/tex] - change in velocity
[tex]t[/tex] - time
Therefore, acceleration can be defined as the rate of change in the velocity of an object.
