Explanation
The correct answer is B because the FATF recommendations state that financial institutions should provide feedback to the FIU as quickly as possible, especially in cases involving the financing of terrorism that could imply an imminent threat to the country. Option A is incorrect because requesting an official court subpoena would delay the response and might not be necessary for the FIU to access the information. Option C is incorrect because establishing a committee would also delay the response and might not be in compliance with the FIU's request. Option D is incorrect because informing the public relations department is irrelevant to the question and might compromise the confidentiality of the investigation.
