Can you provide an example scenario? The general response to an answer, however, would be 답변 감사합니다. If you want to add more to it, you can put an adverb in front of 답변, such as 빠른 답변 감사합니다 (thank you for your quick reply) or 상세한 답변 감사합니다 (thank you for your detailed answer).

thank you for clarifying
