Answer: C - He repaired his mother’s-in-law car. Answer C is not correct because “mother-in-law” is a singular term and the possessive is formed by adding an apostrophe and “s” at the end. Answer A and Answer B are both correct because they are singular terms and the possessive is correctly formed by adding an apostrophe and an “s” at the end. Note that this grammatical rule applies to acronyms.
