A Ubhaya Vakra Sampurna raga is defined by:
Zig-zag (vakra) melodic phrases present in both the ascending (Arohanam) and descending (Avarohanam) scales.
Containment of all seven swaras (notes) in both ascent and descent, characteristic of a sampurna raga.
Ritigoula exemplifies this classification, exhibiting vakra movements in both arohanam and avarohanam, and encompassing all seven swaras.
Analysis of Alternatives:
(A) Mohanam: Classified as an audava raga (utilizing five notes), it is neither sampurna nor vakra.
(C) Kedaragoula: Features vakra movement exclusively in the avarohanam, not in both scales.
(D) Saveri: An audava–Sampurna raga; it does not display vakra movement in both directions.
Consequently, the appropriate selection is option (B).
