Which of these sentences shows the correct use of the comma with coordinate adjectives? A. She was prepared for a long, arduous journey. B. She was prepared for a, long arduous journey. C. She was prepared for a long arduous, journey. D. She was prepared for a long arduous journey.

I believe the correct answer is A.

A

Explanation:

B uses the comma too early in the sentence. C puts the comma too late. D has no comma at all, so obviously A is the right answer. Here is a hint. Try saying the sentence to yourself, and when it is time for the comma, pause for a second, then continue with the rest. Most of the time, the sentence that uses it properly sounds right.
