Which sentence correctly uses a comma?

A.
She drove from Las Vegas, Nevada.
B.
She drove, from, Las Vegas, Nevada.
C.
She drove from, Las Vegas Nevada.

A. She drove from Las Vegas, Nevada.

The correct sentence that uses a comma is option A: "She drove from Las Vegas, Nevada."

The correct sentence that uses a comma is A. "She drove from Las Vegas, Nevada."

To understand why this is the correct sentence with a comma, it's important to know the rules for using commas in this context. Commas are used to separate two or more items in a series, to separate independent clauses, or to provide clarity in a sentence.

In sentence A, the comma is used to separate the city, "Las Vegas," from the state, "Nevada." This helps to provide clarity and indicates that the city and state are distinct elements.

Sentence B uses commas excessively, making the sentence confusing and incorrect. The excessive commas around "from" and "Las Vegas" disrupt the flow and meaning of the sentence.

Sentence C incorrectly places the comma after the preposition "from." Commas are not typically used after prepositions unless there is a need for clarity or emphasis, which is not the case in this sentence.

Remember to use commas appropriately to enhance clarity and ensure correct punctuation.
