Choose the incorrect pair of homophones from the options given below:

The correct answer is Option (4) → Recourse, Resource

Homophones are words that sound the same but differ in meaning and usually in spelling. Recourse (re-KORSE) means a source of help in a difficult situation; resource (re-SORSE or REE-sorse) means a supply of something useful, such as money, materials or skills. The middle sounds "k" and "s" differ, so the two words do not sound alike and are not homophones.
Example: Water is a precious resource.

Why the Other Options are Incorrect?

Option 1: Peace, Piece — Incorrect. Correct use: peace is calm or freedom from war; a piece is a part of something. Both sound "peess".

Option 2: Pane, Pain — Incorrect. Correct use: a pane is a sheet of glass in a window; pain is physical or mental suffering. Both sound "payn".

Option 3: Maze, Maize — Incorrect. Correct use: a maze is a confusing network of paths; maize is corn. Both sound "mayz".
