There is only one measure of "evolutionary success": having more offspring. A "useful" trait gets conserved and propagated by the simple virtue of there being more next-generation individuals carrying it and particular genetic feature "encoding" it. That's all there is to it.
One can view this as genes "wishing" to create phenotypic features that would propagate them (as in "Selfish Gene"), or as competition between individuals, or groups, or populations. But those are all metaphors making it easier to understand the same underlying phenomenon: random change and environmental pressure which makes the carrier more or less successful at reproduction.
You will sometimes hear the term "evolutionary successful species" applied to one that spread out of its original niche, or "evolutionary successful adaptation" for one that spread quickly through population (like us or our lactase persistence mutation), but, again, that's the same thing.
It would be B. Less force is needed to move up the ramp

Explanation:
In a circular economy, good/services/monetary object is in continuous usage up till its maximum value. The good/services/monetary object keep on moving from one service life (one user) to other service life (other user) as they are regenerated and recovered at the end of each service life.
In option A, thrift store has been used to its full extent in one service life and then it is donated (start of second service life)
Hence, option A is correct
