4. when you're working with a word processing document and you press the del key, what happens?
a. the character to the right of the cursor is deleted.
b. the paragraph you're working on is deleted.
c. the entire document is deleted.
d. the formatting style is deleted.

When you're working with a word processing document and you press the Del key, C. The entire document is deleted.

I have actually tried doing this to know which choice is the correct answer. I opened a new document, typed some words then pressed the Del key NOTHING HAPPENED! The character to the right of the cursor was not deleted, the entire document was not deleted, nor was the formatting style deleted.

I chose letter C because after seeing that nothing happened in an open document, I saved said document and opened the folder where the document was saved. I selected the document and pressed the Del key... a prompt appeared asking me if I was sure that I want to move my file to the Recycle Bin? I clicked yes... the entire document is deleted

Malware, not sure what else would fit that description.
