Solution

The correct option is C
80

Instantaneous velocity:
Instantaneous velocity is defined as the rate of change of position for a time interval that is very small (almost zero).
Find the Instantaneous velocity at $0 s$ :
When a body moves with a uniform velocity it covers equal distances in equal intervals of time.
The body moves with the same velocity throughout its course.
Hence, the instantaneous velocity at 0s is $80 k m h^{- 1}$
Therefore, the correct option is option C.
