No way to tell. The liquid in the tank shows acceleration, not velocity.

None of them. The cab is clearly empty. There's no driver.

All three could be.
Or all three could be stopped.
A) Accelerating in reverse or parked on a slope facing downhill
B) Driving at absolute steady rate or parked on a level space
C) Accelerating forwards or parked on a hill facing upslope.

There are a few assumptions here, but C*.
*Assuming the truck is climbing the Alps on a constant grade at a constant speed.

"is" not "are" - unless you are implying there is more than one correct answer.

A could be moving in that direction and braking
B after some time at a steady pace
C accelerating up to speed
All could be the answer as already stated.

B, assuming a perfectly smooth road and constant speed.
A is when breaking a C is when accelerating.
Inertia.

Only B because it has a direction arrow. A and C must be parked on hills.

IRL itβs B
This is because tankers have baffles to stop A & C happening. They could cause instability of the vehicle

Depends... Accelerating, decelerating, rolling but neither accelerating nor decelerating. In each case, the vehicle is moving.
