Answer:
E) buyers and sellers being more interdependent.
Explanation:
The internet has completely changed our world in so many ways that few people could imagine that currently you can purchase Coke directly from a Coca Cola factory, you don't even need to go to a supermarket anymore (and the prices are lower). Slowly but steadily, intermediaries are being eliminated, anyone can remember how huge Sears, Kmart, JC Penny, Macy's were just 10 -15 years ago.
Now manufacturers try to sell their products directly or they use Amazon, Ebay or some other website. And customers like that because the prices are lower now. You can go to a Best Buy store and compare prices with Amazon, and if Amazon is cheaper, you leave the store and your TV arrives the next day.
