the sold _____ eggs yesterday? A several dozen B several dozens C several dozens D several dozen of

答案选哪个，为什么
选C不可以吗

A

several dozen exercise-books
几打练习本

[作为实数及用作定语时, 复数不加“s"

貌似选项里面没有正确选项。应该是several dozens of

选b。和hundred(百)、thousand（千）的用法一样，比方200个人，就是two hundred people（hundred不加s），而hundreds of people是数百人的意思。同理，这里要么是two dozen eggs，要么是dozens of eggs，dozen是12个。
