What information about the salesperson must be included on a completed purchase contract?
Answer: C — Their full name and the first 8 digits of their license number
It is important for the salesperson's full name and the first 8 digits of their license number to be included on a completed purchase contract in order to ensure proper identification and licensing. Option A may not provide enough information for proper identification, while option B may not be necessary and could potentially compromise the salesperson's privacy. Option D is not relevant to the purchase contract and could potentially be seen as discriminatory.
