Concept:
Kathakali is a classical dance-drama tradition of Kerala known for its elaborate makeup, expressive acting, and powerful musical accompaniment. The Kathakali orchestra includes percussion instruments such as the Chenda, which produces loud and energetic rhythmic patterns suitable for dramatic presentation.
Step 1: Examine the Assertion statement.
The Assertion states:
\[
\text{``Kathakali Orchestra includes instrument like Chanda, a harsh drum.''}
\]
This statement is correct because Kathakali performances prominently use:
• Chenda
• Maddalam
• Chengila
• Ilathalam
The Chenda is a loud percussion instrument that creates intense dramatic effect during performance.
Step 2: Examine the Reason statement.
The Reason states:
\[
\text{``It enhances the effect of characters performed under Minukku Vesham.''}
\]
This statement is incorrect because:
• Minukku Vesham represents soft, gentle, and refined characters.
• Loud and harsh percussion such as the Chenda is mainly associated with heroic, aggressive, or powerful character presentations.
Minukku characters generally require subtle and graceful accompaniment rather than harsh rhythmic emphasis.
Step 3: Determine the correct option.
Since:
• Assertion (A) is correct
• Reason (R) is incorrect
the correct answer is:
\[
\boxed{\text{(A) is correct but (R) is not correct}}
\]
Hence:
\[
\boxed{\mathrm{(C)}}
\]
