9. Which one of the following sentences is punctuated correctly?


A. Darleen chose Tara, Holly, and, Marlene as her lab partners.
B. She kept my surprise a secret, but she had a hard time doing it.
C. Della arrived on time, it was just two o'clock.
D. I found a large, smooth, rock on the beach yesterday.

The correct answer is C. The sea calmed but no boats left shore.

To determine the correct punctuation, we need to identify the sentence that has the appropriate use of commas. Let's analyze each option:

A. The sea calmed; but no boats, left shore.
In this sentence, the semicolon (;) is incorrectly used before "but." Additionally, the comma after "boats" is unnecessary and disrupts the flow of the sentence.

B. The sea calmed, but no boats left shore.
This sentence correctly uses a comma "," before "but." However, it is missing a comma after "boats."

[C. The sea calmed but no boats left shore.]
This sentence is punctuated correctly. It does not use any unnecessary commas or semicolons.

D. The sea, calmed, but no boats, left shore.
In this sentence, unnecessary commas are used around "calmed" and "left shore." These commas disrupt the sentence structure and should be omitted.

Therefore, the correct option is C. The sea calmed but no boats left shore.
