flow from form to planner and assign the task based on a response

[Anonymous]

Hi, I am stuck on a flow. I built a flow that takes a form and enters it as a task in planner. My issue is that I want to be able to have the task assigned to someone based on the answer to a question in the form.  I also want the ability to have multiple people assigned if the user selects more than one person. 

For example: 1. Who should be involved in this task?

a) Bob

b) Tom

c) Fred
