Which change, if any, is needed to the underlined text?

The correct answer is B. park. There.

The underlined text "park, there" suggests a comma splice, which is a grammatical error that occurs when two independent clauses are joined with just a comma. Changing it to "park. There" separates the two independent clauses into separate sentences, which is grammatically correct.

So, the correct revision would be “park. There.”
