Which of the following is correct regarding an unlicensed assistant?

An unlicensed assistant can attend a property viewing with an agent and witness the agreement because this activity does not involve any direct participation in the real estate transaction. It is essential for an unlicensed assistant to refrain from activities that require a real estate license, such as preparing an offer, negotiating terms of the sale, signing contracts on behalf of the agent, or installing a lockbox. Additionally, booking showing appointments directly with the seller involves direct communication related to the transaction, which should be handled by a licensed real estate professional.
