Ravi:

The highest priority should be given to the needs of the sales department, because without successful sales the company as a whole would fail.

Ed:

There are several departments other than sales that must also function successfully for the company to succeed. It is impossible to give the highest priority to all of them Ed criticizes Ravi's argument by pointing out:

• AThat the sales department taken by itself is not critical to the company's success as a whole  
• BThe ambiguity of the term "Highest Priority"  
• CThat the department other than sales are more vital to the company's success  
• DAn absurd consequence of its apparent assumption that a department's necessity earns it the highest priority  
• EThat Ravi makes a generalization from an atypical case
