💡 Detailed Explanation
The correct choice is Option 2: 'No, I still have a long way to go.' In Japanese culture, when paid a compliment, it is standard and polite to respond with humility/modesty. 'いいえ、まだまだです' (No, not yet / I still have room for improvement) is the most natural, idiomatic formula. Option 1 ('はい、上手です' - Yes, I am good) sounds arrogant. Option 3 ('どういたしまして' - You're welcome) is a response to thank you, not to a compliment.
