In Florida, the disclosure of brokerage relationship must be made:

Option A is incorrect because waiting until closing is too late. Disclosure must occur before any agreements are signed or property is shown, allowing clients to make informed decisions about representation throughout the entire transaction.

Option C is incorrect because Florida does not have a 10-day disclosure requirement. The timing must be before or at the time of entering into an agreement, not within a specific timeframe after first contact.

Option D is incorrect because disclosure is mandatory in Florida, not optional. Brokers must proactively disclose their relationship regardless of whether the party requests it.
