The question states 'Verum arivala vettinal than kolai, ithu' which means 'Only with intelligence can one kill, this is...' The correct answer is 'vatham' (D), which means principle, logic, or reasoning in Tamil. This makes sense because the sentence is saying that killing (or defeating someone) requires intelligence/principled thinking, not just brute force. The other options (Vitham - method, Kadham - rhythm/beat, Madham - temple) don't fit the context as well as vatham.
