Concept:
In Indian classical performing arts, Natya refers to dramatic representation that combines dance, music, expression, and acting. Nritya, the expressional aspect of dance, forms an essential component of Sanskrit Natya traditions. The technical structure of Nritya evolved through concepts explained in the Natyashastra such as Karanas, Charis, and Angaharas.
Step 1: Examine the Assertion statement.
The Assertion states:
\[
\text{``Nritya is an indispensable aspect of Sanskrit Natya''}
\]
This statement is correct because Sanskrit Natya integrates:
• Dance
• Expression
• Music
• Acting
Nritya plays an essential role in conveying emotions and dramatic meaning.
Step 2: Examine the Reason statement.
The Reason states:
\[
\text{``Nritya has evolved out of Sanskrit Natya in terms of Karanas, Charis, Angaharas etc.''}
\]
This statement is also correct because:
• Karanas are basic dance units
• Charis are leg movements
• Angaharas are combinations of movements
These concepts described in the Natyashastra form the technical foundation of classical dance and Nritya.
Step 3: Determine the relationship between Assertion and Reason.
The Reason correctly explains why Nritya is an indispensable aspect of Sanskrit Natya because Nritya developed directly from the technical and expressive framework of Natya.
Therefore:
• Both Assertion (A) and Reason (R) are correct
• Reason (R) correctly explains Assertion (A)
Hence, the correct answer is:
\[
\boxed{\text{Both (A) and (R) are correct and (R) is the correct explanation of (A)}}
\]
Therefore:
\[
\boxed{\mathrm{(A)}}
\]
