Answer:
D. By removing the jargon
Step-by-step explanation:
The term jargon refers to the terms used by people who work in a certain field. These terms are usually not easily understood by people outside of that field. For example, doctors will use their own jargon, and someone who isn't a doctor will probably not understand what they're talking about.
Donna revised the given sentence by removing the jargon. She decided to omit the words user and subject, making the language easier to understand.
