Which of the following can be a response provided by the Authorization Response?

The response option indicating "Transaction approval or denial" is fundamental to the authorization process in electronic transactions. When a transaction is initiated, the payment processor or financial institution assesses several factors, such as the cardholder's available credit, account status, and potential fraud indicators. The outcome of this assessment is conveyed through the authorization response, which directly informs the merchant whether to proceed with the transaction or decline it.

This response is critical, as it determines the transaction's progression. An approval allows the merchant to finalize the sale, while a denial prevents the transaction from occurring, protecting both parties involved. The clear binary nature of this response aligns with the essential role of authorization processes in ensuring secure and accurate financial transactions.

Other options that involve endorsements, follow-up actions, or card retrieval requests do not directly pertain to the immediate authorization response. Instead, they might be part of subsequent transaction management but are not fundamental aspects of the authorization phase.
