Definitely choose C. Scammers are everywhere these days—it's far too easy to fake things on Moments. Real founders wouldn’t have the time to privately message people everywhere just for a few bucks. Anything like this—“a free meal falling from the sky”—is absolutely a pig-butchering scam. If you encounter something like this, block them directly or verify through official channels. That’s the safest approach—never transfer money impulsively.
