Answer:
Step-by-step explanation:
The most appropriate options for dealing with the situation of an unusually large number of internal transactions in a dealing desk would be options e) (Write a "please explain" email to the division manager and copy this email to most people on the trading room floor, risk management, and operations) and d) (Refer the matter to internal audit in preparation for a potentially prompt spot check on this desk).
Option e) ensures that the division manager is informed and accountable for the situation, and involving relevant stakeholders such as the trading room floor, risk management, and operations helps to raise awareness and gather information.
Option d) involves referring the matter to internal audit, which can conduct a thorough investigation and potentially perform a spot check on the desk promptly. This action helps ensure compliance and identifies any potential issues or irregularities.
By choosing options e) and d), you address the issue promptly, involve the necessary parties, and initiate the appropriate actions to investigate and rectify the situation.
