Bridges operate in datalink layer and are used to connect LANs. More or less they are obsolete now.

Because Bridge is use to connect two dissimilar Lan.

You haven't mentioned that whether they are same type of LANs or two dissimilar LANs.

If they are similar then the answer is Bridge
or if they are Dissimilar then answer is Router.

Bridge provide LANs. To LANs connectivity. Because they are operate in data link layer.

The main work of bridge is to convert the protocol from one LANs to another. Means support the different interface to work.

Modem provides bi-directional data communication Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet. Modem is a device which convert the digital signal to.

Analog single and Analog signal to digital. The use of.

Modem in networking is to connect your computer to internet.

Using telephone line.

Routers are small physical devices that join multiple networks together. Technically, a router is a Layer 3 gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model.

Network repeaters regenerate incoming electrical, wireless or optical signals. With physical media like Ethernet or Wi-Fi, data transmissions can only span a limited distance before the quality of the signal degrades. Repeaters attempt to preserve signal integrity and extend the distance over which data can safely travel. A network repeater is a device used to expand the boundaries of a wired or wireless (WiFi) local area network (LAN).

A bridge has a foot in each network and acts on the link layer (level 2). It is able to pass frames from one network to another in an intelligent manner. A bridge, after a period of learning, is able to identify MAC addresses of nodes on each side of the bridge. It prioritizes the frames that actually need to be transferred, so that the traffic on each side is best. A bridge is very effective if the two networks A and B hardly communicate with each other; otherwise, it is best to communicate with an Ethernet cable for example.

Bridge is basically used to connect two topological different type of LAN segments. It also works on L2 layer. So Bridge is right answer.

Faisal said: (Jul 5, 2013)  
Data link layer makes frames and error detection and work with physical layer (wire, wireless) , bridge (use to join two similar networks) operates on this layer so bridge the answer.

Harinder said: (Jan 28, 2014)  
It says from one LAN to another LAN, so you need router not a bridge.

Lalit said: (Apr 8, 2014)  
Bridge is a l2 device which provide 2 LAN communicate on the network.

Vikas Pandey said: (Nov 24, 2014)  
Bridge it provide a to PC communication in the network.

Why router is a wrong answer?

Vinayak said: (Jan 31, 2015)  
Router is wrong because asking for frames and frames are developed in data link layer, in which bridge or switch works while router is working on network layer(packet).

Anup Joshi said: (Mar 6, 2015)  
Bridges working in data link layer and bridges are used to connects the LAN segments.

Ishtiaq Ahmed said: (Apr 7, 2016)  
The correct answer is B.

Because Bridge is used to connect two LANs environment.

Samawiki said: (Nov 17, 2016)  
How does a bridge operate on the physical layer and data link layer? Please explain.

Eunnynjoro said: (Jul 13, 2017)  
Bridge allows multiple different networks to communicate.

Sid said: (Jul 18, 2017)  
Bridge, router, gateway, everything in network link similar or dissimilar types of network. But the decision of correct device always confused me. I can't differentiate them.
