Solution

The correct option is A Both statement 1 and statement 2 are correct and statement 2 is the correct explanation of statement 1.
Retardation is equal to the time rate of decrease of velocity.
$\Rightarrow$ Retardation $= - \frac{d v}{d t}$
So, when there is retardation, velocity decreases.
This retardation will be oppositely directed to velocity.
