The correct option is D Richard Rosario's child has no hair.
Let’s examine the sentence: “Richard Rosarios child has no hair.” The sentence indicates that Richard Rosario possesses a child or is father of a child, who “has no hair.” It talks about Richard Rosario but the use of ‘Rosario’ with an ‘s’ gives an impression that the surname is ‘Rosarios.’ In order to correct this and indicate possession of the child by Richard Rosario as a father, apostrophe needs to be inserted between ‘Rosario’ and ‘s.’ Apostrophes show possession. An apostrophe is normally used with the letters to show ownership or possession. With most singular nouns, simply add an apostrophe plus the letter s to do this. An apostrophe plus s is never added to make a noun plural--even a proper noun. So, the correct way to present this sentence is, “Richard Rosario’s child has no hair.” Hence, Option C is the correct answer.
