Answer: B. How many vehicle accidents are caused by teens aged 16 to 18?.
Explanation: a claim is a statement that is told as a true, it can be based on facts or it also can be an opinion. In this case the research question that would best help support the claim that the legal driving age should be raised to 18, is the one that asks how many vehicle accidents are caused by teens aged 16 to 18, because if this number is considerable, then it would be prudent to raise the legal driving age.
