Final answer:
A yellow and black sign with a red octagon and a forward arrow signals a No Entry for vehicles in the direction of the arrow. So, the correct answer is option B.
Step-by-step explanation:
A yellow and black sign with a red octagon and a forward arrow typically indicates a No Entry restriction for vehicles. The red octagon is universally recognized as a stop sign, and in conjunction with a directional arrow, it is meant to inform drivers that they cannot proceed in the direction indicated by the arrow.
Traffic signs such as these play a critical role in ensuring road safety by regulating the flow of traffic and protecting pedestrians. The use of universal signage helps drivers from different regions understand traffic rules when they are in unfamiliar places. So, the correct answer is option B.
