NDA (II) 2024 General Ability Test · Question 4 of 141

Correct — A, essential. 'Incidental' means occurring as a minor or secondary accompaniment — not central or necessary; its opposite is 'essential' (absolutely necessary, fundamental). 'Adventitious' (accidental, coming from outside) and 'subsidiary' (secondary, of lesser importance) echo 'incidental', and 'serendipitous' (happening by happy chance) is about luck, not necessity — so none of them is the antonym.

• (b)adventitious — 'Adventitious' means arising accidentally or from an outside source — close in sense to incidental, not its opposite.
• (c)serendipitous — 'Serendipitous' means occurring by a fortunate chance; like 'incidental' it stresses chance, so it is not the antonym.
• (d)subsidiary — 'Subsidiary' means secondary or of lesser importance — a synonym of incidental, pointing the same way.

Antonym item: 'incidental' (minor, non-essential, occurring by the way) versus 'essential' (necessary, central); the distractors reinforce the sense of minor/accidental.
