@Oladamola1 @renabaddie_ Car 3 needs to drive in REVERSE not forward!
English

@debraipp @renabaddie_ It's not wrong because you feel you can't drive out from there if you're in that situation

@Oladamola1 @renabaddie_ Wrong! The questions states only 1 car can reverse. 4 cannot reverse because 5 is behind it. The only car that can reverse is 3 which opens the way for 1 & 2, then 4 & 5, and finally 6 & 7.
English

The correct answer is Car 4.
Here's why:
Car 2 is blocked by Cars 1, 3, and 4.
Car 3 is blocked by Cars 2 and 6.
Car 5 is blocked by 4.
Car 6 is blocked by 5, 3, and 7.
Car 7 is blocked by 6.
Car 1 can't move because 2 is in front.
If Car 4 reverses, it clears the intersection:
Car 5 can move.
Then Car 6 can move.
Then Car 7 can move.
After that, Car 3, 2, and finally 1 can all proceed.
Answer: Car 4.
