Looking for a plugin conditional form

Hello i’m looking for a specific plugin for diagnostic.
People fill a form with different field, for exemple “What is your problem on your car? Wheels – motor ” and many other fields
People send the form then receive an email with a specific content for each field they complete. For exemple products for mechanical problem specific and a phrase “you have motor problem, we can give you some advices.

It’s like making an email that change according to the choice of the user.
