Solution

The correct option is A
Truck

We know that, kinetic energy K.E $= \frac{1}{2} m v^{2}$
where $m$ and $v$ are mass and velocity of the body respectively.

Here as the velocity is constant, K.E is directly proportional to mass.
As the truck has more mass, it will have the highest kinetic energy.
