Answer:
C) Use of Pathos
Explanation:
The author uses "Pathos" to connect two ideas in order to create a comparison or contrast the reader can easily identify through an emotional response. In this case "Just as it is wrong for governments to allow the sale of diamonds that fund a war effort," clearly states that it is a contradiction to use the bloody money of selling such diamonds in order to "legally" combat the exploitaion of those very diamonds. Such a statement compared with "it is wrong for jewelers to buy these diamonds." sets the viewpoint that both parties are incurring in a criminal action given the fact that it is well-known the illegal origin of these diamonds. In the end, it can be inferred that a third party is involved "unwillingly", that is, the end user, the customer who buys a diamond believing its source is legal, not knowing that "unwillingly" is abettor of the extraction of "blood diamonds". Pathos is intended to evoke this exact kind of emotions: surprise, anger, disgust, frustration, etc.
