Assuming Rishabh Swara as Shadaj in the Swaras of Raga Kafi, the swaras of which Raga will be found:

Correct option is A

Correct Option: a)
In Hindustani music theory, shifting the tonal centre or 'Sa' to another note of a scale is a conceptual exercise to discover equivalent modal structures. This process reveals how the same set of intervals can produce different ragas when perceived from a new fundamental.
Information Booster:
· The scale of Raga Kafi is: Sa, Re, komal Ga, Ma, Pa, Dha, komal Ni, shuddha Ni “Ṡ”.
· When Rishabh “Re” is assumed as the new Shadaj “Sa'”, every note's functional identity changes relative to this new base.
· The new scale becomes: Sa' (old Re), komal Re' (old komal Ga), shuddha Ga' (old Ma), Ma' (old Pa), Pa' (old Dha), komal Dha' (old komal Ni), shuddha Ni' (old shuddha Ni).
· This resulting scale— Sa, komal Re, shuddha Ga, Ma, Pa, komal Dha, shuddha Ni—is the exact scale of Raga Bhairavi.
Additional Knowledge:
· Raga Todi would require a different intervalic structure (e.g., shuddha Ga and shuddha Dha are not present in this transformation).
· Desi is not a standard primary raga matching this scale.
· Bilawal requires all shuddha notes, which is not the case here.
