Yes B should be the answer here...
Supercilious and presumptuous mean similar that is to show more than one actually is..
And so pretentious is the correct choice..

B

OA is incorrect
Please intimate the source and explanation or the OA will be changed.

Carcass's explanation is correct. The OA is 'disagreeable'.

Please intimate the source, explanation and logic.
There is no logic in choosing word 'disagreeable'. If we are missing out something, please give the logiv

I also selected B.

However after checking the OA, I presume that the word should contradict "admire" and similar to "presumptuous".
Supercilious is "thinking oneself superior to other" and hence does not contradict "admire".
So the other word would be the opposite of "admire".

A. thrifty: miserly, not wasteful. DOES NOT CONTRADICT "admire"
B) pretentious: ostentatious, pretending to impress. DOES NOT CONTRADICT "admire" but very similar to "presumptuous"
C) disagreeable: unfriendly, disliked. LITTLE OFF but CONTRADICTS "admire" and similar to "presumptuous"
D) libelous: defamatory. DOES NOT CONTRADICT "admire"
E) disinterested: showing no interest. DOES NOT CONTRADICT "admire"

So, the best bet seems C

I've read all the explanations and the oscillation between those who choose pretentious and disagreeable is confusing. I chose pretentious because "seldom regarded him as being anything but presumptious."

The reason why B is not the answer is that it is awkward to have adjectives with same meaning twice, as if "Mike is fool and stupid", leading to a redundancy.

Carcass. B seems to be the answer, nowhere in the question does it seem to be fit that Disagreeable is a useful to the context of the question.

Pretentious seems to be more closely apt to this question.

Explanation

The sentence describes an actor with a widely known negative reputation. The blank is linked to "supercilious manner" and the fact that others regard him as "presumptuous."

Supercilious = behaving as though you think you are superior to others; arrogant.
Presumptuous = overconfident; failing to recognize your own limits; arrogantly forward.


Both of these clues point directly to a personality that is self-important, overly showy, or arrogant.
Pretentious means attempting to impress others by appearing more important, talented, or cultured than one actually is. It perfectly aligns with "supercilious" and leads logically to the public perception of being "presumptuous."


Why the others are incorrect:
A. thrifty - means economical or careful with money; completely unrelated to arrogance or reputation.
C. disagreeable - means unpleasant or bad-tempered. While a pretentious person might be disagreeable, "disagreeable" does not specifically connect to "supercilious" or "presumptuous" (which are about arrogance, not just general unpleasantness).
D. libelous - means defamatory (involving false written statements). This describes accusations, not a personal manner.
E. disinterested - means impartial or unbiased; unrelated to arrogance.
