A
TCP/IP (Transmission Control Protocol/Internet Protocol)
B

Explanation: 

Detailed explanation-1: -TCP/IP specifies how data is exchanged over the internet by providing end-to-end communications that identify how it should be broken into packets, addressed, transmitted, routed and received at the destination.

Detailed explanation-2: -There are four layers of the TCP/IP model: network access, internet, transport, and application. Used together, these layers are a suite of protocols.

Detailed explanation-3: -The four layers of the TCP/IP Model include Network Access Layer, Internet Layer, Host to Host Layer, and Application Layer.

Detailed explanation-4: -IP is the main protocol within the internet layer of the TCP/IP. Its main purpose is to deliver data packets between the source application or device and the destination using methods and structures that place tags, such as address information, within data packets.

Detailed explanation-5: -Transmission Control Protocol (TCP) is a standard that defines how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.
