Why this is the answer
The correct answer in the official bank: Stop before the intersection and wait for traffic to clear.
You must not enter an intersection unless you can drive through it and leave it without getting stuck inside. A vehicle stopped in the middle of the intersection blocks cross traffic and causes jams and danger. So you stop before the intersection and wait until it clears. A green light or an intended left turn does not allow you to enter an intersection that is not clear.
