I asked John about the issue, but he just pulled my leg instead of answering my question.

The idiom "pulled my leg" means to tease or joke with someone, which doesn’t fit well in the context of avoiding a question. "Beat around the bush" means to avoid giving a direct answer, which fits the context of not answering the question directly.Meanings of other idioms: Gave me the cold shoulder – To ignore or be indifferent to someone.Bit off more than he could chew – To take on more than one can handle.Put his foot in his mouth – To say something embarrassing or inappropriate.Since John didn’t answer the question directly, option (c) is the best replacement.
