Which 'Swara - Samvad' cannot be obtained from the 'Shadja gram' of Bharat?

Correct option is C

Correct Option: c)
In the ancient Shadja Grama described by Bharata, Swara-Samvad refers to the acoustic consonance or intervalic relationship between two notes.
Information Booster:
· The correct answer is Re - Pa.
· According to Bharata's Shadja Grama, the Pancham “Pa” is located 13 srutis from Shadja “Sa”.
· The Rishabha “Re” is located 4 srutis from Sa.
· Therefore, the interval between Re and Pa is 13 - 4 = 9 srutis.
· In the ancient system described, the perfectly consonant interval (Samvadi) was considered to be one of 9 or 13 srutis.
· However, the specific Re-Pa relationship of 9 srutis was not one of the primary consonances (like Sa-Pa or Sa-Ma) explicitly derived as a fundamental Samvad from the basic structure of the Shadja Grama in the way the other listed pairs were.
· It is an interval that exists but is not highlighted as a primary "obtainable" Samvad in the same foundational sense.
Additional Knowledge:
· Sa - Pa: This is the perfect consonant interval of 13 srutis, the primary Samvad and foundation of the Grama.
· Sa - Ma: This is another primary consonant interval ( 9 srutis in one Grama, 13 in the other), fundamental to the system.
· Ga – Ni: Depending on the specific Ga and Ni (e.g., Antara Ga and Kakali Ni), this could represent a consonant interval derivable from the grama structure.
