Final answer:
At an intersection, the recommended sequence before pulling out is to look left, then right, and left again, known as the left-right-left rule. Thus (option b) is right answer.
Step-by-step explanation:
When you come to an intersection and intend to make a move, you should follow the left-right-left rule before you pull out. This procedure involves looking to your left first to ensure no vehicles are coming, then to your right, and then left again before proceeding.
It must be noted that while 'left-right-left' is a widely recommended approach, rules and recommendations may vary by location and drivers should always follow the specific instructions of their local road authority and the traffic situation present. Thus (option b) is right answer.
