B)It will change to the right-hand lane to continue straight ahead since the line delimiting the lanes is broken.Correct
C)It will continue straight ahead without leaving the lane it is travelling in.
The red vehicle may change to the right-hand lane and continue straight ahead because at the point where it is, the road marking delimiting the lanes is broken.
If the road marking were continuous, it would be obliged to turn left even if that were not the direction it wanted to take.
