The correct option is
A extreme, judgement
Option A: 'Extreme' means 'of the utmost or highest degree'.
'Judgement' means 'the forming of an opinion or conclusion as from circumstances presented to the mind'.
It is relevant to the given sentence in meaning: With the realization, we have found ourselves with moral values of the highest degree and little ethical judgement.
The sentence presents a contrast between 'moral values' and 'ethics'.
Hence option A is correct.
Option B: 'Fundamental' means 'an essential part of, a foundation or base'.
'Scruples' means 'a restraining force that inhibits certain actions'.
Option C: 'Incidental' means 'happening as a result of an activity'.
'Standard' is 'a rule or principle used as a base of judgement'.
Option D: 'Obsolete' means 'no longer in general use'.
'Direction' means 'the line along which anything lies or moves'.
Option E: 'Stereotypes' means 'settled in form', 'conventional'.
'Perspective' means 'the state of one's ideas'.
The words do not form a complete and meaningful sentence.
Hence options B, C, D and E are wrong.
