The correctly punctuated sentence is:
B. He asked when she would arrive to deliver the roses, hyacinths, begonias, and carnations for the graduation ceremony.
The answer "B. He asked when she would arrive to deliver the roses, hyacinths, begonias, and carnations for the graduation ceremony" is correctly punctuated because it uses commas to separate items in a list. In this case, the list consists of different types of flowers: roses, hyacinths, begonias, and carnations.
The use of commas in a list is a common punctuation rule. When you're listing items in a sentence, it's essential to use commas to separate the items, which makes the sentence easier to read and helps avoid confusion. The comma before the coordinating conjunction "and" (which appears before the last item in the list) is known as the "serial comma" or "Oxford comma," and it's a style choice that is often recommended to prevent ambiguity, especially when the items in the list are more complex.
So, the answer "B" demonstrates proper punctuation by correctly separating the items in the list using commas, making the sentence clear and grammatically correct.
I hope this helped!
