Concept:
Every classical North Indian rhythmic cycle (Taal) is defined by its total beat count (Matras), structural sub-divisions (Vibhags), claps (Tali), waves/empty beats (Khali), and standard mnemonic syllables (Theka Bols).
Step 1: Analyze the total number of Matras for each given option.
Let us review the total beat capacity of the respective rhythmic cycles:
• Sool Taal = 10 Matras
• Ektaal = 12 Matras
• Rudra Taal = 11 Matras
• Pancham Savari = 15 Matras
Step 2: Verify the placement of syllables within the full rhythmic layout.
Since the question directly points to a syllable sequence residing on the \(12^{\text{th}}\) matra, the cycle must contain at least 12 counts. In the traditional configuration of Ektaal (12 matras), the foundational mnemonic string finishes its sub-vibhag distribution within its 12-beat span, making it the mathematically and structurally correct choice.
