This question was previously asked in
UPSSSC Lower PCS 2026 Question Paper (23-Aug-2026)
The correct answer is

Application → Transport → Internet → Network Access

The TCP/IP model has four layers, and reading them from the top, that is from the software the user touches down to the physical wire, fixes the order.

The Application layer sits at the top and carries protocols such as HTTP, FTP, SMTP and DNS that programs use directly.

Below it the Transport layer, using TCP or UDP, breaks the data into segments and manages end-to-end delivery between processes.

Next the Internet layer, using IP, addresses and routes packets across networks.

At the bottom the Network Access layer handles framing and physical transmission on the local medium, corresponding to the data link and physical layers of the OSI model.

Hence, the correct top-to-bottom sequence is Application → Transport → Internet → Network Access.
