ok.
I have power to a switched box that i will wire to my compressor. i
have 4-strand 6 gauge cord.
problem is compressor has 2 hot and a ground, no neutral. what do i
do with my white wire?

Don't use it. It isn't needed for a 240V circuit.

my googling came up with:
A. attach it to the breaker along with the black.
Wrong.
(sounds sketchy, why not just not use it)?
Indeed.
B. ground it at the compressor. Sounds better but ?
Also wrong.
Any help would be great.

Don't connect it to anything at either end. Put a wire nut on each end so that
there's no possibility that the conductor might come in contact with anything
live.
