Concept:
A standard musical octave layout (Saptak) divides pitch space into notes based on their tonal properties. Distinguishing between foundational micro-tones (Shrutis) and basic scale notes (Swaras) is crucial for analyzing these systems.
Step 1: Evaluate Assertion (A).
Assertion (A) states that a single octave (Saptak) is composed of 7 natural notes (Shuddha Swaras: Sa, Re, Ga, Ma, Pa, Dha, Ni) and 5 altered notes (Vikrut Swaras: Komal Re, Komal Ga, Teevra Ma, Komal Dha, Komal Ni). Summing these components yields the 12-note chromatic pitch system used in Hindustani music:
\[
\text{Total Notes} = 7 \ (\text{Shuddha}) + 5 \ (\text{Vikrut}) = 12 \text{ Swaras}
\]
This makes Assertion (A) correct.
Step 2: Evaluate Reason (R).
Reason (R) states that there are a total of twenty-two Swaras inside a Saptak. This statement contains a key terminology error. In classical music theory, there are exactly 22 Shrutis (micro-tonal intervals) within an octave, which are condensed into 12 Swaras (notes). Because the statement refers to twenty-two Swaras instead of twenty-two Shrutis, Reason (R) is factually incorrect.
