Option (D)

Correct Option:
C
Question Solution:
Out of which/that, "that" will be the option. "That" specifically identifies who or what you're talking about."Which" is used to describe the person or thing you're discussing, but it is not essential to the meaning of your sentence.
You can test usage of that/which by asking yourself these questions: If I take out the clause, does my sentence's meaning remain the same? If it does, you should use "which." If the meaning changes, use "that." Does the sentence call naturally for a comma? If it does, this might be a signal that you need to use "which."
Out of "to keep/keeping" option will be "keeping". "to keep" does not fit because of "excercising".
Because we are talking about brain parts (plural) next 2 options are simple.
Hence answer is option (c)

Option (C)

Option (D)
ABBA
Correct Option:
D
Question Solution:
First sentence: the phrase has to be "differ from " and not "differ to".
Second sentence: Author is talking about "national governments (plural)" and hence correct word will be "their".
Third sentence: It starts from "their top managers". That means author is talking about companies referred in previous 2 sentences. Previous sentences are in past tense & hence here it should be "were" and not "are". In second half of same sentence we can see usage of "are" but there it is for "modern multinationals".
For the second half of sentence 3, it starts with "whereas" that means it is trying to show a differencd between first half & second half of sentence. In first half suthor says about "substantial minority share" for owners. So in second half it will be much less for senior managers. Hence correct option is "insignificant".
