I believe the answer is A. This is because the sentence is supposed to be parallel and all of the verbs(except for hiss) have to be past tense.
Answer:
B. The weather was frigid in Minnesota; it wasn't warm at all.
Explanation:
An antonym is the opposite word or meaning of a given word. It gives the exact opposite or different meaning of what is implied by a word.
In the context of the word "frigid", the antonym will be "warm, hot, pleasant," etc. And among the given statements, sentence B uses the antonym context of the word "frigid". While the other three statements give the implication of the coldness of Minnesota, the second sentence uses the antonym "warm" to add a different aspect of the coldness of the place.
Thus, the correct answer is option B.
