Correct answer: C

Concept: Networking entries of this kind are separated by two questions — at which layer does the item work, and do the two sides it joins speak the same protocol? A bridge is a data-link-layer device that joins segments running one and the same LAN protocol. A router is a network-layer device that examines the addressing information of incoming data and forwards it onward to different networks. A gateway is the protocol translator placed on the boundary of a network, so traffic enters and leaves the network through it. A standard is not equipment at all: it is a published set of rules that machines must obey in order to interwork.

Application: Take each entry of LIST-I in turn and read off the description it demands.

  1. Bridge works at the data-link layer and joins one LAN to another LAN running the same protocol, which is the description numbered IV.

  2. Router reads the destination address of arriving data, consults its routing table and sends the data onward to other networks — receiving, analysing and transmitting, the description numbered I.

  3. Gateway stands where a network meets a differently built network and converts between their protocols, so all traffic enters and leaves through it: the description numbered III.

  4. Ethernet (IEEE 802.3) is the wired-LAN standard that lays down how stations are cabled together and how they share the medium; it is a set of rules, the description numbered II.

Cross-check: Each description is used exactly once, and the deciding feature differs in every row.

LIST-I entry

LIST-II

Deciding feature

Bridge

IV

Same protocol on both sides

Router

I

Analyses data and forwards it to other networks

Gateway

III

Boundary of the network, protocol conversion

Ethernet

II

A standard, not a piece of equipment

Contrast: Ethernet is the only entry of LIST-I that names a standard rather than a piece of equipment, so the sole "set of rules" description must belong to it. Among the three devices, "same protocol on both sides" pins the bridge, "analyse and transmit to other networks" pins the router, and "entry and exit point" pins the gateway. The matching is therefore A-IV, B-I, C-III, D-II.
