A dealer can assess an additional service fee for what specific reason?

Answer: A — Completing any sales-related or lease-related vehicle inspections or forms required by law if the dealer has made full disclosure of the service fee

Option B is incorrect because providing complimentary car washes is not a legally required service and would not justify an additional service fee. Option C is also incorrect because adding air fresheners would not fall under completing inspections or forms required by law. Option D is incorrect because it directly contradicts the statement in the question about an "additional service fee" and performing no additional services would not justify such a fee. Option A is the only option that aligns with the given context and would justify an additional service fee for a dealer.
