Which of the following sentences is punctuated correctly?

A. Melissa said that she would never go on a cruise
B. Justin asked, "Will tickets be available online"?
C. "Of course," Mr. Howard replied "You can buy tickets and rent a car online."

I think it is A.

None of those is correct. A would be right if it had a period at the end.

Which of these sentences is punctuated correctly? (Points : 1)

The nursery rhyme begins this way: Mary had a little lamb . . . And everywhere that Mary went, the lamb was sure to go.
The nursery rhyme begins this way: “Mary had a little lamb. . . . And everywhere that Mary went, the lamb was sure to go.”
The nursery rhyme begins this way “Mary had a little lamb…And everywhere that Mary went, the lamb was sure to go.”

Actually, the correct answer is C.

Option A is missing a comma before the closing quotation mark. It should be: Melissa said, "that she would never go on a cruise."

Option B is correctly punctuated with a comma before the closing quotation mark.

Option C is also correctly punctuated. It starts with a quotation, followed by a comma and a closing quotation mark. Then, there's a capital letter to begin the dialogue of Mr. Howard, followed by a comma and another quotation mark to close his dialogue.

Yes, you are correct. Sentence A is punctuated correctly.

To determine the correct punctuation, let's analyze each sentence:

A. Melissa said that she would never go on a cruise.
In this sentence, there is a direct statement, so no punctuation is needed except for the ending period.

B. Justin asked, "Will tickets be available online"?
In this sentence, there is a direct question, and when a quotation marks a direct question, a question mark is used inside the quotation mark along with a closing punctuation mark like a period, exclamation point, or question mark outside the quotation mark. So, this sentence should be punctuated with a question mark after "online" and a closing quotation mark at the end of the sentence.

C. "Of course," Mr. Howard replied "You can buy tickets and rent a car online."
In this sentence, there are two direct statements. Each statement should be closed with a closing quotation mark and, if needed, be followed by a comma before continuing the dialogue tag. So, the sentence should be punctuated like this: "Of course," Mr. Howard replied, "You can buy tickets and rent a car online."

Therefore, the correctly punctuated sentence is indeed A.
