Registration Forum Custom Questions: Multiple-choice Answer Options

I've only recently joined and this is already my second question...to clarify, I don't intend to continue this cadence going forward ;-)

Registration form. Custom questions. The multiple-choice variant. Is there a maximum number of answer options that I can offer, or is it unlimited? I've found info on the maximum character count for the question, and for each answer option here:

https://community.logmein.com/discussions/gotowebinar-discussion/custom-registration-question---answer-character-limit/257486

but the participant (Ken4) in that earlier thread had also asked the question I'm asking today, and I don't see that it got answered.

TIA!
