Step-by-step explanation:
The question pertains to the duration an individual must hold their instructional permit before they can qualify for a driver's license. This duration varies depending on the age of the individual. For a person who is 18 years old, they must hold their instructional permit for at least six months. If the individual is 19 years old, the period is shorter, requiring them to hold their permit for just three months. So, the correct answer is A) Six, three.
