The Boolean operator OR expands the number of results when used in a keyword search. Thus, the correct option is D.
<h3>What is the Boolean operator?</h3>
The Boolean operator may be defined as an important tool that is utilized in the programming languages for the junctions to integrate or exclude keywords in a search, resulting in more attention and generative outcomes.
The Boolean operators are major of three types with specific functions and properties. They are:
Therefore, the Boolean operator OR expands the number of results when used in a keyword search. Thus, the correct option is D.

Answer:
Selective Repeat protocols
Explanation:
It is better to make use of the selective repeat protocol here. From what we have here, there is a high error rate on this channel.
If we had implemented Go back N protocol, the whole N packets would be retransmitted. Much bandwidth would be needed here.
But we are told that bandwidth is limited. So if packet get lost when we implement selective protocol, we would only need less bandwidth since we would retransmit only this packet.
The answer is 2-to-the-power-of-n, since for every input, the number of different combinations doubles. From your list I think answer A is meant to indicate 2ⁿ.
