Critical Reasoning

Clearly, while comparing two companies, higher sales do not necessarily indicate higher profits. A recently published article in a prominent business magazine shows that the top ten names on the list of companies with the highest sales and the corresponding names on the list of companies with the highest profits are mutually exclusive.

Which of the following can properly be inferred based on the above statements?

A) While comparing two companies, the company with higher sales is more likely to have lower profits.
B) It is highly likely that two companies with different sales have the same profit margins.
C) Sales and profits have no correlation.
D) While comparing two companies, lower sales do not by themselves indicate lower profits.
E) In order to compete in the market, it is better for a company to have higher profits than higher sales.

Need clarification on choices C and D.
Experts, please reply.

The passage offers information about a SAMPLING of companies: those with the highest sales and those with the highest profits.
C makes a claim about ALL companies: that there is NO correlation between sales and profits.
This claim does not have to be true.
It is certainly possible that sales and profits are correlated for companies NOT included the passage's limited sampling.
Eliminate C.
