Step 1: Understanding the Concept:
The question requires arranging the given Carnatic Jatis in descending (decreasing) order based on their 'Akshara' count (number of beats).
Step 2: Detailed Explanation:
First, let's list the Akshara count for each Jati:
- (A) Sankeerna (Sankirna): 9 aksharas
- (B) Chaturasra: 4 aksharas
- (C) Mishra: 7 aksharas
- (D) Khanda: 5 aksharas
Now, let's arrange these in decreasing order (from largest to smallest):
1. Sankeerna (9)
2. Mishra (7)
3. Khanda (5)
4. Chaturasra (4)
This corresponds to the sequence A, C, D, B.
Step 3: Final Answer:
The correct decreasing order of Aksharas is Sankeerna, Mishra, Khanda, Chaturasra.
