The correct answer is option 3), i.e. Renu said, "Give me a pen, a pencil, and a book." Explanation: The given sentences are written in direct speeches.
The first sentence is not correctly punctuated as no 'quotation mark' is used while introducing the reported speech.
The correct sentence: Renu said, "Give me a pencil and a book."
Hence, option 1) is not the correctly punctuated sentence.
In the second sentence, 'comma' should be used after the reporting verb 'said' and the word 'pen'.
The correct sentence: Renu said, "Give me a pen, a pencil, and a book."
Hence, option 2) is not the correctly punctuated sentence.
In the fourth sentence, the 'quotation mark' should be used to write the reported speech and a comma should be used after the reporting verb 'said'.
The correct sentence: Renu said, "Give me a pen, a pencil, and a book."
Hence, option 4) is not the correctly punctuated sentence.
Only the third sentence is appropriately punctuated. Hence, option 3) is the answer.
