Final answer:
A buyer's agent is a real estate professional who represents only the interests of the buyer in a transaction, regardless of who pays their commission. Option A.
Step-by-step explanation:
The correct answer to which type of real estate agent represents only the buyer is A. Buyer's agent. A buyer's agent is a professional who is legally licensed to represent the interests of the buyer in a real estate transaction.
This differs from a seller's agent, who represents the seller, a dual agent who represents both parties, and a listing agent who has a contract with the seller to list the property.
Regardless of who pays the commission, whether it is the buyer, the seller, or it is split with the listing agent, the buyer's agent's obligation is to the buyer.
So Option A.
