what about  D 

[Deepak Kumar]

D:  It simultaneously delivers multiple streams of data.

But multicast is not delivers multiple streams. It is for single stream for multiple devices.

from the initiator it is single stream, when it branches out...each intermediate device duplicates the stream and sends out in each of its interface which is nothing but multiple streams of one input. 

I am new to networking, let me know if i am wrong...

[LvSrikanthLakshman]

The question says simultaneous delivery, not initiation. However, the catch could be...the delivery cant be simultaneous though its multiple stream...

Answers are:
C  becasue it is, indeed, bandwidth intensive.

E   in IPv4, it is the most efficient way to deliver data to multiple receivers.

Can't be D because it is a single stream of data.

IP Multicast Basics

IP multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to potentially thousands of corporate recipients and homes. Applications that take advantage of multicast include video conferencing, corporate communications, distance learning, and distribution of software, stock quotes, and news.
