Long story short I wanted to meet with this girl on weekend and texted her: "Do you have any plans for the weekend?" And she replied: "Yes"

I know that wording of this question was shit, I should have put this question differently, but I don't know whether this response is a shit test or a rejection. I know that she is out getting drunk with her besties right now, so I decided to just ignore this response and wait until tomorrow when she will be alone and sober.

So here is my question for you guys: Should I:

A. Treat this response as a shit test and text her tomorrow with precise question regarding the date?

B. Treat this response as a shit test, soft next her, and then set a date (after 2 weeks or so)?

C. Treat this response as a rejection and hard next her?

Or any other solution?

Any advice will be appreciated.
