Emailing Specific information from MS forms with Flow.

Hello all,

You have helped me a great deal recently so  I thought i would ask 1 more questions.

I have a form, which once you get through the initial "who are you" questions, gives you 3 options for audits to fill out. I'm trying to set it up in Flow that if they select Audit 1 it sends this email format and if they select audit 2 it sends a diff format and so on. I can not figure it out. I feel like i have to use an expression but I've never done that. 

Any help would be greatly appreciated.
