I think the answer is option B.

While braking road wheels of the vehicle are observing two tractional forces one parallel to the motion of the vehicle and other perpandicular to the motion of the vehicle. The perpandicular force by defination won't do any different in the direction of the car. But parallel force can make locked wheel to decelerate less as compaired to unlocked wheel. In both cases wether it is front or rear wheels locked the back-end of the vehicle is goind to rotate but in case of rear wheels locked the rotation of the back-end is more than front wheels locking up.

D. Driver loses control over the steering, and the vehicle continues moving in its current direction.

When the front wheels of a vehicle are locked during braking, the vehicle can lose steering control, and it will continue moving straight in the direction it was travelling instead of following the driver’s input.

This is why anti-lock braking systems (ABS) are used to prevent the wheels from locking and maintain control.

Option B is correct, logically rear wheels brake are generally used to balance vehicle while braking, if rear wheel brake are not effective then vehicle gating unbalance in high speed Results it is spins around.

I think the answer is B.

How the vehicle continues its motion in the same direction while the front wheels locked?

Bracks are locked how vehical moves when vehical movement steering will works.

Yes, I too agree option B is the correct answer.

I think the answer will option B. Am I right?

@Majeed.

It's Because of inertia.

I think the answer is B.
