选B绝对正确!
it's +形容词+of sb to do （此形容词是修饰sb的）
如 it's very kind of you to say that.
it's +形容词+for sb to do （此形容词是修饰to do sth的）
如it's necessary for you to finish it now.
to finish it now is necessary
不是you are necessary.

d

选B

B 表示某人性质用of，raise for为固定搭配，表示募集（钱款）

B. of; kind 是修饰you 的。可以构成主语和表语的关系，因此选of.
to raise so much money for us. 是真正主语。开头的it 是形式主语！

B.of,to raise
固定句型 it + be + adj. + of /for sb. to do sth.。
如果前面adj 是修饰人 就用 of

b
