Help connecting speaker wire!

[Echolane]

This feels like a dumb question, but I’m stumped. I had to send out my tube amp for a repair. I am substituting a modified vintage Pioneer to use in the interim snd I am baffled as to how to connect the speaker wire to the amplifier.

The speaker wire has one red wire and one black wire. The Pioneer receiver has two red posts and two black posts. Which pair of posts should I choose?

Use 'A'. Then use the red/black pair on the left for the left speaker, and the red/black pair on the right for the right speaker. Obviously, attach the red wire to the red terminal, and the black wire to the black terminal.
