breakout rooms

I scheduled a meeting for next month, anticipating aprox 20 participants. I want to use breakout rooms for this meeting (10 groups of two participants) yet when I go to meeting options, there is no place to select reassign breakout sessions.

Questions:

1. Does the $149 annual membership level include Breakout options?   
2. must participants be registered in the zoom meeting prior  to the meeting? If so, how is this done in advance of the meeting date?

3. How do i know, i have the capability to offer Breakout rooms prior to my meeting?

thanks, MindyM
