Correct option is C
Correct Option: c)
Information Booster:
· The correct sequence is C: Dhwani, Naad, Shruti, Swara, Saptak.
· Dhwani is a generic, audible sound.
· Naad is that subset of Dhwani which is musical and resonant.
· Shruti is the microtonal interval discernible in Naad.
· Swara is the musical note selected from the Shrutis.
· Saptak is the octave containing the series of seven Swaras.
Additional Knowledge:
· Other sequences are illogical. For example, starting with Swara or Saptak puts the structured element before the fundamental component (Dhwani/Naad), reversing the causal and conceptual order.
