Virtual Audio Cable confusion

[tentenrabbit]

Hi. I have two questions to ask on which VAC to get. Under two circumstances :

1. Stream game on Twitch, headphone mic + Adobe Audition, and voice chat on Discord
2. Stream game on Twitch + in game chat, Audobe Audition and headphone mic

Will the basic VAC (https://vb-audio.com/Cable/) be enough or do i need to get the A+B / C+D?
