What document signifies acknowledgment of an application and includes the responsible officer's details?

The document that signifies acknowledgment of an application and includes the responsible officer's details is the acknowledgment receipt. This document serves a crucial purpose in the application process, as it indicates that the application has been successfully received by the relevant authority. By including the details of the responsible officer, the acknowledgment receipt establishes a point of contact for the applicant, ensuring clarity and communication. This aspect is vital for addressing any potential follow-up questions or additional requirements related to the application.

In comparing this with other choices, a certification letter typically serves to confirm the successful completion of training or qualification rather than merely acknowledging receipt of an application. A registration approval letter would indicate that an application has been approved, which comes after the acknowledgment phase. An application summary report typically provides a detailed overview of the application itself, rather than focusing on the acknowledgment of its submission. Therefore, the acknowledgment receipt is the most appropriate choice for signifying recognition and including pertinent contact information.
