"B"

moving forward

Backwards

Forward

I'm not sure, but I will said c) not moving at all.

The reason is the front wheel look not moving, but the rear wheel moving by the backward. It's weird because I never saw a motorcycle having a rear speed.

"A"

It is moving forward sliding as it brakes the dirt from the front of the back tire proves that its moving forward not backwards!

C

The back wheel is spinning backwards, but the front wheel is standing still. So, the bike is not moving at all

moving backwards

The answer is C,  it is not moving

backward

As it's a Ducati and judging by the exhaust smoke it's just blown up - which isn't unusual for Ducati (mine did it twice!). I'm saying C - it's not moving forwards or backwards, the front wheel isn't moving, given that the back wheel is blurred to show motion I'd say it's doing a burnout.

BACKWARD

a) forward

c.
