[Grammar] who or whom?

[maoyueh]

As a non-native speaker, I would like to check with English language experts to see whether "who" can be used instead of "whom" in the following cases? Which of the following sentences are correct? Thank you very much.

a. Who to invite to my wedding party is an important thing to me.
b. Whom to invite to my wedding party is an important thing to me.
c. It is an important thing to me who to invite to my wedding party.
d. It is an important thing to me whom to invite to my wedding party.

It seems to me all are correct. Please correct if I am wrong. Thanks a lot.

"Whom" would be grammatically correct, but you would seldom/never hear it used in that context (AmE). So, feel free to use "who".

Note that "is an important thing to me" is rather unnatural.

Who/whom to invite to my wedding [reception] is important to me.
