"find it + (to be/ x) + adj" or "find +noun phrase + as adj"

[PhuongD794]

In Q680 SC - OG 2018, I have a concern regarding the grammatical structure "find it .....". There are 3 structures displayed as following:

1/ find it + adj + if SVO....
2/ find it + to be adj + if SVO....
3/ find + Noun phrase + as adj

As far as I'm concerned, (1) is grammatically correct, but I'm not sure about the other two structures. Hence, in this question, this split is unnecessary in elimination process, therefore, I cannot determine whether the last two are correct. Any expert/ native speaker please share some thought?

Besides, I wonder whether the 3 above structures are true if the part "it" is replaced by a noun phrase, and vice versa?
e.g. whether "find + noun phrase + adj" is grammatically justified?

Thank you.
