Final answer:

Explanation:
The recommended action when merging onto a highway from an entrance ramp is B.) Wait for a break in traffic large enough to maintain the speed of traffic. This action allows you to safely join the flow of traffic at the same speed as the highway vehicles. It's important not to speed up and merge into traffic quickly or merge into traffic regardless of the speed of approaching vehicles as it can create a dangerous situation. Coming to a complete stop at the end of the entrance ramp is also not advised unless there's a stop sign or traffic conditions require it, because a sudden stop can cause a hazard for approaching vehicles.
