The novelist has a hold of — in writing.

✅ কেন সঠিক: A novelist is known for his or her ‘style’ of writing — the way of expressing ideas. So ‘has a hold of style in writing’.

❌ অন্য অপশন: Manner, history and tradition do not fit the collocation with writing skill here.

💡 মনে রাখুন: style = writing manner unique to a writer.

📖 শব্দার্থ: অর্থ: ঔপন্যাসিকের লেখার রীতির ওপর দখল আছে।
