$\begin{array} {}  \text{a.} & \text{Data link Layer} & \text{i.} & \text{Flow Control} \\  \text{b.} & \text{Network Layer} & \text{ii.} & \text{Node to node delivery} \\  \text{c.} & \text{Transport Layer} & \text{iii.}&  \text{Mail services} \\  \text{d.} & \text{Application Layer} & \text{iv.} &\text{Routing } \\ \end{array}$

$\textbf{Codes :}$

• A. $\text{a-ii, b-i, c-iv, d-iii}$
• B. $\text{a-ii, b-iv, c-i, d-iii}$
• C. $\text{a-ii, b-i, c-iii, d-iv}$
• D. $\text{a-ii, b-iv, c-iii, d-i}$

Answer 1

Answer : B

a. Data link layer                   ii. Node to node delivery
b. Network layer                    iv. Routing
c. Transport later                   i. Flow control 
d. Application layer                iii. Mail services  

Application Layer :  It consists of protocols that focus on process-to-process communication across an IP network and provides a firm communication interface and end-user services

Transport Layer :  The protocols of the layer provide host-to-host communication services for applications.

Network Layer : The network layer is responsible for packet forwarding including routing through intermediate routers, since it knows the address of neighboring network nodes

Data Link Layer : This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment.
