Final answer:
Marshall provided Dolly with a protective list in a real estate scenario. Dolly's next-door neighbor should not be included on the list.
Step-by-step explanation:
In this scenario, Marshall is a real estate broker and Dolly is his client. They have a listing agreement with a six-month override clause, which means that Marshall has the right to receive his commission even if another agent brings in the buyer after the listing agreement expires within six months.
Marshall provided Dolly with a protective list, which is a list of people who are exempt from the override clause. The purpose of this list is to protect Dolly's interests and ensure that she does not have to pay Marshall a commission if the sale is made to someone on the list.
Based on the options given, the person who should NOT be included on the protective list is Dolly's next-door neighbor. Typically, a next-door neighbor does not have any legal or financial interest in the property being sold, and therefore, they would not be exempt from the override clause.
