Choose the correct homonym pair:

The correct answer is Option (2) → Birth-Berth

The pairs here are homophones (a kind of homonym): words that sound the same but differ in spelling and meaning. Birth and berth are pronounced alike.

• Birth means the act of being born.
  Example: The birth of their daughter brought great joy.
• Berth means a sleeping place on a train or ship, or a place for a ship in a harbour.
  Example: I booked a lower berth on the night train.

Why the Other Options are Incorrect?

Option 1: Career-Carrier — Incorrect. The words sound different: career (a profession) is stressed on the second syllable, carrier (one who carries) on the first.

Option 3: Confident-Confidant — Incorrect. Confident (sure of oneself) and confidant (a person one trusts with secrets) differ in the final syllable and are not true homophones.

Option 4: Eligible-Illegible — Incorrect. Eligible (qualified for something) and illegible (not readable) sound quite different.
