Final answer:
An agency disclosure pamphlet is not required if a customer only requests a commission quote or a Comparative Market Analysis, as there's no establishment of an agency relationship. It's generally needed when an agency relationship is being established, despite customer preferences against it.
Step-by-step explanation:
An agency disclosure pamphlet is typically required in real estate transactions to inform clients of the agency relationships and representation in a transaction. In the presented scenarios, an agency disclosure pamphlet would not be required if a customer only requests a commission quote and does not provide contact information (a), or if a customer steps into the office and only asks for a Comparative Market Analysis (CMA) (d), as there is no establishment of an agency relationship just based on these inquiries. The choice (b), where a customer requests not to receive a pamphlet, generally is not correct because the requirement to provide an agency disclosure pamphlet is governed by state laws and industry regulations, which typically mandate that the pamphlet must be provided regardless of the customer's preference. Therefore, answer (c) 'None of these require an agency disclosure pamphlet' is not the correct answer because in other circumstances, when an agency relationship is being established or discussed, it would be required.
