Which of the following is a correct pair of singular and plural?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Hypothesis:Hypotheses
Plural of nouns ending in -is:
Some nouns that come from Greek change -is to -es in the plural. Crisis becomes crises and basis becomes bases. In the same way hypothesis → hypotheses. A hypothesis is an idea that is not yet proved and has to be tested.
Why the Other Options are Incorrect?
Option 1: Horse:Horse — Incorrect. Horse is a regular noun. It takes -s. Horse → Horses.
Option 2: Stomach:Stomaches — Incorrect. Here -ch sounds like “k”, so the noun takes only -s. Stomach → Stomachs.
Option 3: Pony:Ponys — Incorrect. Pony ends in a consonant + y. The y changes to -ies. Pony → Ponies.
