Who needs to take the course discussed?

Answer: A — All first time drivers in Florida

The reason A is the correct answer is because the course discussed is likely a mandatory safe driving course in Florida, which all first time drivers must take. While commercial drivers may also be required to take a safe driving course, there is no indication that the course being discussed is specifically for them. Similarly, while bicycles and pedestrians should also always prioritize safe driving practices, they are not usually required to take a course on it. Therefore, A is the most accurate and specific answer.
