I'm a senior high school student in Egypt. It's from a final revision book called al-adwaa

I don't understand what you mean by that, but let's put it aside.

she has worked here since three years ago
or
she worked here since three years ago

No. If you read the question carefully, you'll see that it says "... since her graduation, three years ago".
The temporal "since" is used with a point in time (here, it's the graduation).
It (since) refers to a period in the past, starting from a particular point. Thus, the present perfect is the correct option.
Note that the past perfect (had worked) might work too, but the right context is needed to justify that.

Sorry I was confused when I reread that too. I meant it like, while using since(not changing the temporal), Which is correct?
And thanks! my teacher said it was the past simple and it just felt wrong. out of curiosity, In what context can we use the past perfect in this case? and is there a way to use the past simple with the temporal "since"? Thanks a lot again!

while using since which is correct I still don't understand this incomplete sentence.

1. She has worked here since three years ago.
or
2. She worked here since three years ago.

(as in The whole thing is in the past and she has stopped working.
I came across it in an MCQ.
I know it's better to just use "for".

Option 1 is just about usable, but not in this context.
Option 2 is incorrect because the past simple is the wrong tense.

Neither of them is appropriate if she doesn't work there anymore.

She started working here three years ago but she has now left/retired.
