From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.
Their _____ house is by the side of the road.
-
father-in-law's
- father's-in-law
- fathers-in-law
- father-in-laws
The correct answer is: A
Explanation
The sentence refers to a house belonging to their father-in-law. To form the possessive of a compound noun like "father-in-law," the apostrophe and "s" are added to the last word ("law"), not to "father." A. father-in-law's is correct because it shows possession: Their father-in-law's house is by the side of the road.
