B. Rory Hill, an EMT who writes on the subject, said that "the older a young person is before being given the privilege to drive, the safer our roadways will be."
This is the best option for a sentence which integrates the information. This quote is introduced with an effective setup that identifies the speaker. The appositive phrase "an EMT who writes on the subject" describes Rory Hill. Option A is not correct because it doesn't sound correct. Also, the parenthetical citation should be followed by a period. Option C plagiarizes the quote because there are no quotation marks around the quotation. Option D is wrong because a parenthetical citation is not needed since the speaker of the quote is identified in the quote's setup.
