no brainer

Decision requiring nothing

A no brainer is a decision or choice that requires little or no thought because the answer is obvious.

The term suggests that even someone without much mental effort could see the right course of action.

Accepting the job offer was a no brainer—the salary was double what I was making.

It's most often used when one option is so clearly superior that deliberation seems pointless.
