Why does a bus topology require a terminator

The purpose of the terminator is to absorb signals so that they do not reflect back down the line

Explanation:

The answer is-

B.) because otherwise the packets will bounce back and forth from end to end repeatedly

Bus topology can be regarded as a kind of topology for a Local Area Network, it is one that has it's nodes connected to a single cable(backbone) and any break in the so called backbone, there will be failure in the entire segment. However a Terminator is usually attached to the end-points of a bus network so that the signal is absorbed by the Terminator and as a result of this the signal will not reflect back down the line. If there is no Terminator there would be bouncing back and forth of packet in an endless loop.It should be noted that a bus topology require a terminator because otherwise the packets will bounce back and forth from end to end repeatedly
