this is one of the book which_?_?_sold in that bookstore.

A.is B.are c.have D.has

Answer 1

B 题目应该是这样的吧：
This is one of the books which are sold in that bookstore.
d答案选择B
which引导定语从句，修饰前面的books，这里book是复数名词，因此be动词用are。be+过去分词，表示被动。

Answer 2

A

Answer 3

one of 后接可数名词复数， 表示什么中的一个，动词用单数第三人称。
One of the apples has gone bad.
但是要注意下面的定语从句：
He is one of the boys who enjoy playing basketball.定语从句修饰the boys。
He is the only one of the boys who enjoys playing basketball.one前面有定冠词the的时候，定语从句是修饰one的，所以动词要用单三形式
