Select the correct form of the word in the following sentence. Although John's
boat was at the landing, the boy was nowhere in sight.
son-in-law's
son's-in-law's
son-in-law
son's-in-law

Although John's boat was at the landing, the boy's son-in-law was nowhere in sight.

Explanation:

The correct form of the word used in the sentence is the third option which is son-in-law.

A son-in-law is the husband of one's daughter or son. The other word forms are incorrect because the plural form of son-in-law is son-in-laws and it is not available in the option.

No form or tense of the word son-in-law has an apostrophe separating any of the words.
