Step 1: Think about how any martial art is taught.
A teacher first builds a strong and flexible body. Then simple tools are given, then harder tools, and last the fight with no tools at all. Kalarippayattu follows this pattern.
Step 2: First stage.
Meithari trains the body with exercises, jumps and oil massage. It is Body Fitness, so C is first.
Step 3: Second stage.
Kolthari uses long wooden sticks and short sticks. It is Stick Combat Training, so A is second.
Step 4: Third stage.
Ankathari moves to sharp metal weapons such as swords and spears. It is Handling Weapons, so B is third.
Step 5: Fourth stage.
Verumkai is the last stage, with bare hand combat and vital points. It is Training in Hand Combat, so D is last.
Step 6: Match with the options.
The order C, A, B, D appears only in option 4. Every other option places body fitness after a weapon stage, which a trainer would never allow.
Step 7: Why a different order would fail.
If a student met sharp metal weapons before learning stick control, injury would be likely. If a student began hand combat before body conditioning, the moves would lack strength and balance. This is why the stages are fixed and why options 1, 2 and 3 are wrong.
Final Answer:
Option 4 shows the traditional training sequence of Kalarippayattu.
\[ \boxed{\text{Option 4: C, A, B, D}} \]
