Solution

The correct option is B Broadcasting

Transmission of a message to all nodes in network is called Broadcasting.

Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model.

Also see unicast, multicast, and anycast. In general, to broadcast (verb) is to cast or throw forth something in all directions at the same time. A radio or television broadcast (noun) is a program that is transmitted over airwaves for public reception by anyone with a receiver tuned to the right signal channel.

Broadcasting is the simultaneous transmission of the same message to multiple recipients. In networking, broadcasting occurs when a transmitted data packet is received by all network devices.

In computer networking, broadcasting refers to transmitting a packet that will be received by every device on the network. In practice, the scope of the broadcast is limited to a broadcast domain.
