Which of the following is a correct pair of singular and plural?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Stomach : Stomachs
Plural of nouns ending in -ch:
Most nouns ending in -ch take -es, as in bench → benches. But when the -ch sounds like k, the noun takes only -s. Stomach ends in a k sound, so stomach → stomachs.
Why the Other Options are Incorrect?
Option 1: Storey : Stories — Incorrect. A storey is one floor of a building. Storey ends in a vowel + y, so it takes only -s. Storey → Storeys. “Stories” is the plural of story, a tale.
Option 3: Tooth : Tooths — Incorrect. Tooth has an irregular plural. The vowel inside changes. Tooth → Teeth.
Option 4: Ox : Oxes — Incorrect. Ox has an old irregular plural with -en. Ox → Oxen.
