问题补充：

---Are you satisfied with the result of the exam?

---Not at all. I can’t have.

A. a worse one

B. a better one

C. the worst one

D. the best one

答案：

(答案→)A. a worse one

B. a better one

C. the worst one

D. the best one

解析：根据Not at all可知，对方并不满意，故本句的意思应是“我不能有一个更糟糕的成绩了。”此处的one（result）是泛指，而C是特指，故应排除。所以本题选A。
