For this assumption to be logical, we have to figure the main thrust of the passage argument and validate it with a truthful answer choice.
Option A - Incorrect
The similarities between pop music and rock music are not relevant to this argument.
Option B - Incorrect
This claim is too absolute. We can't know, according to the passage, if Frenchie Pear's previous singles that got buoyant sales were marketed in Power Records.
Option C - Correct
Yes, this claim is valid. These statements"playing rock music in Power Records increases sales of rock albums" and "playing classical music leads to an increase in sales of classical music albums" from the passage prove that this sales technique work for specific songs.
Option D - Incorrect
The sales techniques used by Power Records are what influence the sales of different genres of music, and not the rave (enthusiastic) reviews gotten om some set of music.
Option E - Incorrect
This is incorrect as there is no such report from the passage to validate this claim on if Power Records sells more pop albums than any other music chain store does. In addition, the argument is not concerned about the record that has the higher sales.
