Question

Choose the possessive case of the noun phrase given in the bracket:
After his foot got fractured, my _________________ mobility has got severely reduced. (father-in-law)

• A. father's-in-law
• B. father-in-law's
• C. father-in's-law
• D. father-in-laws

Answer 1

Answer: (B)

father-in-law's

When a noun consists of several words, the apostrophe+s is suffixed to the last word in the noun.

The hyphenated group of words: "father-in-law" refers to a single noun. Its possessive case is formed by suffixing apostrophe+s to the last word i.e law. Hence, its possessive form is: father-in-law's. Option B is the correct answer.

The other options are incorrect as they do not follow the rule as mentioned above.
