d. Every second, the truck's velocity increases by 3 km/h to the south.

Explanation:

Acelleration can be defined as change of velocity over change of time.

That's why if we say: "A truck accelerates 3 km/h/s south."

We are saying that the acceleration of the truck variate 3Km/h wich is velocity of the truck, and it variates every second and also its direction is south.
