The comparison of the cost of one good to the other can help determine its:

The comparison of the cost of one good to another is central to understanding opportunity costs. Opportunity cost refers to the value of the next best alternative forgone when making a decision. In essence, when choosing to purchase or produce one good, the cost of that decision includes not only the explicit costs but also the value of what you have to give up in order to pursue that option. By comparing the costs of different goods, you can assess what you are sacrificing by not choosing the other option. This concept is vital in economics, as it influences consumer behavior, production choices, and resource allocation.

Fixed costs, average costs, and sunk costs refer to different economic concepts. Fixed costs are costs that do not change with the level of output, average costs involve calculating the total costs divided by the number of goods produced, and sunk costs are costs that have already been incurred and cannot be recovered. While these concepts are important in economics, they do not relate to the direct comparison of the cost of one good to another in the way that opportunity costs do.
