The correct answer is D. An alternative that we sacrifice when we make a decision.
Explanation
"Trade-off" is a term to refer to the action of preferring an option or alternative in a group of possibilities, that is to say, is to decide to get something by sacrificing other available possibilities. An example of this is when you buy a shirt or a jacket because you can choose only one between different colors, textures, sizes, and more features; this implies you sacrifice other options or trade-off the option you selected against other options. So, the correct answer is D. An alternative that we sacrifice when we make a decision.
