单选题 So far as the food industry is concerned, the processing of sheep and lambs is relatively ______ in the United States, accounting for only about 7 percent of meat-packing production.

A. irrelevant
B. appropriate
C. negligible
D. redundant

【正确答案】 C

【答案解析】[解析] 各项的意思为：irrelevant不相关的；appropriate恰当的；negligible可忽略不计的；redundant多余的。由产量紧紧占了百分之七可知产量很少，所以选C。
