Select the most appropriate ANTONYM for the underlined word in the given sentence. Despite his annoyance, Rahul knew that rushing the delicate process would only lead to mistakes.

Correct — C. The word under test is annoyance, an emotion of irritation or vexation. Its opposite has to name untroubled calm.

Serenity is exactly that: peace of mind, freedom from agitation. The sentence sets the contrast up itself, since Rahul is annoyed and still keeps his judgement about the delicate process.

None of the other three options sits anywhere on the calm-to-irritated axis → option (c).

Why the others are wrong

• (a)
  Absurdity — Absurdity means ridiculousness or plain illogic. It judges how sensible something is, not how agitated a person feels.
• (b)
  Susceptibility — Susceptibility is liability to be affected, influenced or harmed. That is a vulnerability, and it is neither the opposite nor the equal of irritation.
• (d)
  Gnawer — Gnawer means one that gnaws, typically a rodent. It names a creature rather than a state of mind, so it cannot be the antonym of an emotion.

An antonym item that supplies a whole sentence is doing two jobs. It fixes which sense of the tested word is in play, and it usually plants the contrast in the sentence itself.

Here annoyance is used in its ordinary sense of irritation, and the sentence sets that feeling against Rahul's cool judgement.

So the answer must be a noun naming calm. Match the word class first — all four options are nouns — then match the axis: calm against agitation.

Key facts

• Serenity means calmness and untroubled composure, the noun from serene.
• Annoyance is mild anger or irritation, so its antonyms name calm rather than pleasure.
• Gnawer is an agent noun from gnaw and names a thing that gnaws, not a quality.

Common traps

• Choosing a merely unrelated word such as Absurdity because the harder options look more likely.
• Answering with a synonym when the stem prints ANTONYM in capitals.
