Broker Andrew is told by his seller-client to keep a small basement water leak confidential because it has never created a problem for the seller. The sellers do not note the leak on a property disclosure statement. Prospective purchasers, Johnston and Joan, while walking through the basement with Andrew, do not notice any visible leaks, but they ask him if there have ever been any problems with water in the basement. In this situation, Andrew: a. Tell the purchasers about the basement water leak.

b. Must respect his duty of confidentiality and say nothing about the leak.

c. Tell the buyers to ask the sellers about any leaks.

d. Advise the buyers to hire a home inspector to check out the basement
