Step 1: Write each taal with its count:
Ek Taal = 12, Jhoomra = 14, Pancham Sawari = 15, Tilwada = 16. These are the standard Hindustani matra counts.
Step 2: Line them up on a number line:
On the number line the values 12, 14, 15, 16 already increase in the order A, C, B, D.
Step 3: Find the option with this letter order:
Option 2 says (A), (C), (B), (D), which is exactly this order.
Step 4: Test the other options quickly:
Option 1 has B before C, so 15 comes before 14. Option 3 begins with B (15), which is not the smallest. Option 4 begins with C (14), but A (12) is smaller. So these fail.
Step 5: Recheck every option once more:
Option 1: (A), (B), (C), (D). This is not the answer.
Option 2: (A), (C), (B), (D). This is the correct choice.
Option 3: (B), (C), (A), (D). This is not the answer.
Option 4: (C), (A), (B), (D). This is not the answer.
Final Answer:
The increasing order is (A), (C), (B), (D), option 2. \[\boxed{2}\]
