正确答案：
C
解析：
According to the given table, a person can obtain a driver’s license at 14 years of age in 7 states and at 15 years of age in 12 states. Hence, there are 7+12 or 19 states in which a person under the age of 16 can obtain a driver's license. Since the total number of states is 50, the percent of the states in which a person under the age of 16 can obtain a driver's license (16/50) × 100% or 38%.
