Answer:
C) Fads have made some business owners incredibly wealthy.
Step-by-step explanation:
Remember Pokemon Go, Angry Birds, the Gangnam Style? Those fads didn't last very long, probably Angry Birds lasted a couple of years, but the rest only lasted a few months, but Nintendo and the Korean guy made tons of money with them. And there are lots of fads we can add to that list: fidget spinners, Crocs, cronuts, etc.
