Explanation

You learn in the second half of this sentence that the documentarian received “money” and “acclaim,” while the subject of the documentary did not. Either one could go in the blank, but because you know it’s coming “from the critics,” it needs to match up with “acclaim” (critics don’t give “money”).

Both approbation and plaudits fit this meaning. Opprobrium and fulmination are the opposite of what you want, and wealth and capital don’t fit the meaning of the sentence.

Hence options approbation, plaudits are correct!
