Which is an example of a correctly punctuated dialogue sentence?

• A. Let's go to the park," she said.
• B. "Let's go to the park," she said.
• C. "Let's go to the park" she said.
• D. Let's go to the park. she said.

Answer: (B)

The main idea is how to punctuate dialogue with a speaker tag. When the speaker’s words come first and are followed by a tag like “she said,” you put a comma inside the closing quotation mark, then the tag in lowercase, and end with a period after the tag. This shows the spoken words and the narrator’s tag are one sentence.

That’s why the correct sentence works: it starts with the spoken part in quotes, has the comma inside the quotes before the tag, then the tag, and a final period after the tag. The other options break this pattern—one misplaces punctuation outside the quotes, one leaves out the comma before the tag, and one ends the quote with a period before the tag, making it two sentences.
