Answer:
Option (c) is correct.
Step-by-step explanation:
Acceleration of an object is given by the formula as follows :
![a=(v-u)/(t)](https://img.qammunity.org/2021/formulas/physics/college/o8v5h6pch5mxd0asdn7oisawa5gpuduncg.png)
Where
u and v are initial and final velocity
t is time
(v-u) is also called the change in velocity
So, the acceleration of an object is equal to the rate of change of velocity. Hence, the correct option is (c) " Change in its velocity divided by the change in time".
