Which two online transactions are acceptable forms to request and reply to a HIT confirmation?

To determine which online transactions are acceptable for requesting and replying to a HIT confirmation, it’s important to understand the specific codes used in this context. The transaction codes typically represent various actions in the system.

The correct answer features YQ for initiating a HIT confirmation request and YR for responding to that request. YQ serves as the request transaction, indicating that a user is asking for confirmation regarding a HIT, while YR is used as the reply, denoting that there is a response to that request. This pairing accurately reflects the communications system for handling HIT confirmations.

In contrast, the other options do not provide the appropriate combination of request and reply codes. YY does not serve a function in this specific context, and while YT is valid for other purposes, it does not designate the confirmation request and response process. Therefore, the pairing of YQ and YR stands out as the correct choice for requesting and replying to a HIT confirmation.
