What is your doubt ??

personal and subjective

Here's my approach to this question

......blah blah.... states that the attempt to find parity(equality) in a relationship is a fallacious(false/misleading) principle, as (implies, next comes a statement/phrase that supports the earlier statement) any notion of fairness is entirely_______________ .

I looked out for words that relating to perception or view. So I could straight away eliminate introverted, utilitarian, pragmatic as they explain the quality of person or thing and not the perception.

Now I'm left with subjective, illicit, personal.

Of the three choices left, it was an easy decision to let go illicit as it couldn't pair with either subjective or personal.

Hence the answers is A,F
