Explanation:
The seven-layered OSI (Open Systems Interconnection) model is used to describe how data is transmitted over a network. Each layer has a specific function and protocols that perform that function. The layers are:
1. Physical Layer
2. Data Link Layer
3. Network Layer
4. Transport Layer
5. Session Layer
6. Presentation Layer
7. Application Layer
SMTP, FTP, and DNS are applications that operate at the highest layer of the OSI model, which is the Application Layer. This layer is responsible for providing services to user applications, such as email, file transfer, and domain name resolution. The Application Layer interacts directly with the user and provides a platform for applications to communicate with each other.
Therefore, the correct answer is option D, Application Layer.
