Given below are two statements: One is labelled as Assertion A, and the other is labelled as Reason R.
Assertion A: Devgiri Bilawal is an Ashraya Rag.
Reasons R: S, N. DS, RGMGRGRGMRGRS, N.DPG, MGRGRS is the clear form of Devagiri Bilawal in Purvang.
In the light of the above statements, choose the correct answer from the options given below:

Correct option is D

Correct Option: d)
An Ashraya Raga is one that gives its name to its parent Thaat (e.g., Bilawal is the Ashraya Raga of Bilawal Thaat). The melodic form (chalan) of a raga describes its characteristic phraseology.
Information Booster:
· Assertion A is incorrect. Devgiri Bilawal is not an Ashraya Raga. An Ashraya Raga is the namesake and basic scale of a thaat.
· The Ashraya Raga of Bilawal Thaat is simply Bilawal.
· Devgiri Bilawal is a variant (jod raga or a specific blend).
· Reason R is correct. The provided phrase "S, N. DS, RGMGRGRGMRGRS, N.DPG, MGRGRS" does indeed represent a clear melodic form (chalan) of Devagiri Bilawal focusing on the Purvang (lower tetrachord).
Additional Knowledge:
· The Reason, while factually describing the raga's phraseology, does not support the false Assertion about it being an Ashraya Raga. Therefore, A is false, R is true.
