Abhinaya means ‘expression’ in Indian classical dance.
There are four types of Abhinaya: Angika, Vachika, Aharya, and Sattvika.
Angika involves gestures and body movements.
Vachika uses speech, song, or recitation.
Aharya includes costume, ornaments, and makeup.
Sattvika represents inner emotions and feelings.
These four work together to make performances expressive and complete.
Thus, the correct answer is 4.
