Explanation: This sentence is correctly punctuated by using commas to separate items in a list (a pair of shoes, a handbag, a dress, and an umbrella). (a) John said, I am ten years old. The correct version should be: "John said, 'I am ten years old.'" The punctuation marks (quotation marks) are needed to indicate the spoken words. (b) Excuse me, are you Mr. Patel? The correct version includes a comma after "Excuse me" to properly separate the introductory phrase. (d) You dress is green mine is red. The correct version is: "Your dress is green; mine is red." This version uses a semicolon to connect related independent clauses. Additionally, the possessive form of "Your" is used. So, option (c) is the only one with the correct punctuation.
