问题补充：

She has set a new record, that is, the sales of her latest book 50 million.

A. have reached

B. has reached

C. are reaching

D. had reached

答案：

(答案→)A. have reached

B. has reached

C. are reaching

D. had reached

解析：因为that is意为“换句话说，即 (=in other words, which means)”，而前句中的谓语has set是现在完成时，后一句的谓语动词也应用现在完成时，排除C和D；又因主语the sales是复数，选出正确答案A。
