To find a correctly punctuated sentence, you should look for a sentence that follows the standard rules of punctuation. These rules include using capital letters at the beginning of the sentence and for proper nouns, using end punctuation such as periods, question marks, or exclamation points, and using appropriate punctuation within the sentence to separate phrases or clauses.

Here is an example of a correctly punctuated sentence:

In this sentence, the first letter is capitalized, the sentence ends with a period, and there are no errors in the internal punctuation.

There are many sentences that can be punctuated correctly. Here is an example of a sentence that is punctuated correctly:

"I went to the store to buy groceries, and then I stopped by the post office to mail a package."
