How do you form the possessive of a singular noun?

• A. Add an apostrophe and the letter 's' to the end of the word.
• B. Add an apostrophe after the word only.
• C. Add two apostrophes.
• D. Add 's without an apostrophe.

Answer: (A)

Ownership on a singular noun is shown by adding an apostrophe and an s to the end. This small marker signals that something belongs to that one noun, as in the student’s notebook, the teacher’s desk, or a dog’s leash. That simple rule covers most cases in everyday writing and exams. Sometimes names or words ending in s invite stylistic preferences—some guides add only an apostrophe after the s (James’ book), while others stick with adding ’s (James’s book). The key point for a singular noun is to use the apostrophe plus s to form the possessive. The other options don’t correctly express ownership for a singular noun: using only an apostrophe after the word, adding two apostrophes, or leaving out the apostrophe and just adding s would not convey possession in standard form.
