Select the correct option:
The finance minister’s statement was laden with caveats, none of _______ were explained.

Correct option is C

The correct option to fill in the blank is (c) which.
Here, “none of ___ were explained” needs a relative pronoun to refer back to caveats (things). The correct structure is none of which, used to add extra information about the noun mentioned earlier. (Hindi meaning: जिनमें से कोई भी)
Example: He made several promises, none of which were fulfilled.
Explain why other options are incorrect:
· (a) that: “none of that” is not used to refer to a plural noun like “caveats” in this relative-clause structure. (Hindi: वह/जो)
· (b) them: “none of them” could be correct in normal speech, but here the sentence requires a relative clause connector after a comma; “none of them were explained” would work without linking as a relative clause. (Hindi: उनमें)
· (d) whom: used for people, but “caveats” are things, so “whom” is wrong. (Hindi: जिसे/जिन्हें)
