一题求教

When drive-ins were at the height of their popularity in the late 1950's, some 4,000 existed in the United States, but today there are less than one-quarter that many.

B. there are fewer than one-quarter as many

C. there are fewer than one-quarter of that amount

D. the number is less than one-quarter the amount

E. it is less than one-quarter of that amount

答案是C。

我选了B。虽然觉得B中的as many怪怪的。

但the amount可以用在这里吗？amount不是多用于不可数名词的量吗？请指正。谢谢先了.

查了longman，

However, people often use amount with plural countable nouns when what they are talking about is thought of as a group: We didn't expect such a large amount of people. | an enormous amount of problems

这个能作为这题选C的理由吗？请指教。
