Decaffeinated coffee is highly costly than that of regular coffee even though the process by which coffee beans are decaffeinated is fairly simple and not very costly. Higher cost for providing decaffeinated coffee to the consumer cannot be accounted for by its producers. Select the assumption on which this argument relies.

A

Price differences between products can generally be accounted for by such factors as supply and demand, not by differences in production costs.

B

There is almost no competition among companies that process decaffeinated coffee.

C

Retail coffee-sellers do not believe that consumers are content to pay more for decaffeinated coffee than for regular coffee.

D

The beans used for producing decaffeinated coffee do not cost much more before processing than the beans used for producing regular coffee.
