Correct Option-b)
Carnatic (Karnataka) and Hindustani music share the same fundamental 12-note system but use different nomenclatures and sometimes different positions for microtonal shades (Shrutis). Antara Gandharam is a specific note in the Carnatic system.
Information Booster:
· 'Antara Gandharam' in Carnatic music is equivalent to Shuddha Gandhar (G) in Hindustani music.
· In Carnatic's 72 Melakarta (parent scale) system, Antara Gandharam refers to the third note that is three Shrutis away from Shadja (Sa). This interval corresponds to a major third.
· In Hindustani music, the note that forms a major third from Sa is Shuddha Gandhar.
· The Carnatic Shuddha Gandharam is actually a different, lower-pitched note, equivalent to Hindustani's Komal Gandhar.
Additional Knowledge:
· Komal ga in Hindustani is equivalent to Shuddha Gandharam in Carnatic.
· Shuddha ma and Shuddha re have their own equivalents (Prathi Madhyamam and Chatusruti Rishabham/Shuddha Rishabham, respectively) and are not related to Antara Gandharam.
