Which sentence is punctuated correctly?

Our cat is independent but also very lovable no?

Your cousin Wendy, really knows a lot about growing indoor gardens, no?

This is the book, about outer space, that you recommended to me yes?

That cartoon with the talking dog is hilarious, yes?

The sentence that is punctuated correctly is:

"That cartoon with the talking dog is hilarious, yes?"

To determine the correct punctuation, we need to look at the use of question tags. Question tags are short phrases that are added to the end of a sentence to turn it into a question or seek confirmation. They usually consist of an auxiliary verb and a pronoun.

In this case, the question tag used is "yes?" which seeks confirmation. It is correctly punctuated by placing a comma before the question tag.

Let's analyze the other sentences for their incorrect punctuation:

1. "Our cat is independent but also very lovable no?" - This sentence is incorrect because it lacks a comma before the question tag "no?".

2. "Your cousin Wendy, really knows a lot about growing indoor gardens, no?" - This sentence is incorrect because it also lacks a comma before the question tag "no?".

3. "This is the book, about outer space, that you recommended to me yes?" - This sentence is incorrect because it places the question tag "yes?" before the closing quotation mark. In English punctuation rules, the closing quotation mark should come before the question tag or any other punctuation marks.

To punctuate this sentence correctly, it should be: "This is the book, about outer space, that you recommended to me, yes?"
