VeraCrypt - Single-boot or Multi-boot?

Just wondering how should I know which option to choose? Either single or multi? I currently have a Windows only drive, and then I have another drive (this drive is a storage drive) with a Mac partition and Mac files stored on it and another partition that has my Windows files stored on it. I have a Hackintosh separate drive but that is down/disconnected for testing, but I plan on getting it up and running later. Is it done by OS per drive or separate drive or something? I don't get it

Is it permanent? Will it break if I choose the wrong option?

Never mind, I got it. I had the wrong settings I was going for.
