The correct answer is B, "A red, rusty gate blocked the opening of the trail."

Coordinate adjectives are in a row and both separately modify the subject. You can rearrange the order of the adjectives without confusion. For example, I could say, "A rusty, red gate blocked the opening of the trail," without changing the meaning or fluency of the sentence. In the other sentences, it is impossible to change the order of the adjectives and still have a coherent, fluid sentence.
