I want to make a form with a question type choice.
Only 15 responders can answer option 1, only 15 responders can answer option 2.
Is this possible? Using flow or something else?

There's no way to do this with Forms as I know you would have discovered.
Flow could count the responses until they hit 15 for option 1 and 15 for option two but I'm not sure how you would stop further responses from there.
Without understanding what option 1 and 2 is about, I can't give you any ideas around a solution as I don't have context around the scenario.
You may want to explore one of the more advanced survey services like Survey Monkey to see if it can do what you want?
