Answer: B; digital etiquette
Step-by-step explanation:
Well, plagiarism is when you steal another's ideas and use them as your own without sourcing.
Piracy is also a form of stealing.
Bias is when you lean towards one idea over another because of preference or experience/feelings.
So the only answer that would work would be digital etiquette because that means doing the proper thing online.
Hope this helps!!! :)
