RC question from a mock test (third party)

Paragraph:

People often talk about a leader’s integrity, sometimes as if it is a
psychological quality and sometimes as if it is a moral quality. The
description of moral integrity has as many definitions as there are writers
in the leadership literature. Leadership scholars often define integrity as
a cluster of moral concepts that usually include honesty

and sometimes they use integrity to refer to all aspects of a leader’s
ethics. The descriptive meaning of the word “integrity” is wholeness and
that wholeness is the umbrella over all aspects of morality or as Aristotle
says, “the rule”. When a person has a virtue, it is a hexis because we do
not expect moral qualities to be selectively exercised or exercised in
isolation from other virtues. As David Baum notes, integrity refers to a
personal completeness that describes a person’s unbroken or uncorrupted
character
Question:

From the information given in the passage, the meaning of the term “hexis”
can be said to be:
A. something that is complete
B. something that is a subjective state
C. something that is unadulterated
D. something that is a gift
E. something that is a dilemma

I chose option A because of the word “because” after hexis which according
to me clearly explains what a hexis is. But according to them the correct
answer is B.

Explanation given by them:

The sentence that the term “hexis” appears in, talks about a person who has
virtue, who in turn is a hexis. The determiner “a” used before the term
gives us the clue that hexis is some sort of a noun. With this information,
we can cancel out options A and C as they are adjectives. The part of the

sentence that follows the term *“..because we do not expect moral qualities
to be selectively exercised or exercised in isolation from other
virtues” *tells
us why a person with virtue is a hexis. This partial sentence suggests that
virtues can’t be applied in isolation. Thus, it most certainly can’t be a
gift (Option D). The most likely options are B and E. Out of the two, a
hexis is more likely to be a subjective state because of the hint given by
the word ‘selectively’ in the sentence. The virtue is not exclusive, it
exists in relation to other virtues, making it subjective.

I disagree with this explanation on so many levels, starting with the fact
that they eliminated options A and C because they are “adjectives”, which
is absolutely not true in this context.

My friend and I had a huge debate about this question and we would be
grateful if you could shed some light on it.

The correct answer is indeed A. I think their explanation is just dumb overall because all the options are noun phrases.

“something that is brown” = noun — “something” characterized by the color brown.

Also ‘a heixis’ refers to virtue, not person.

Finally, if the normal expectation is that moral qualities are not selectively exercised or are not exercised in isolation, that would run counter to being ‘subjective’ since there is no selectivity (if we interpret selection to be a subjective decision).

Yes, I think the same thing. Thank you for replying!
