Step 1: Understanding the Concept:
Sanskrit dramaturgy (Natya-shastra) is a highly categorized field where every element of a play is numbered and defined. Major texts like Bharata's 'Natyashastra' and Dhananjaya's 'Dasharupaka' establish these counts.
Step 3: Detailed Explanation:
1. Abhinayah (Modes of Acting): There are exactly 4 types of Abhinaya.
These are: Angika (Physical), Vachika (Verbal), Aharya (Costume/Make-up), and Sattvika (Internal/Emotional).
Matching: A-IV.
2. Rupakani (Major Dramatic Forms): There are exactly 10 major types of drama.
As the work 'Dasharupaka' implies, these include Nataka, Prakarana, Bhana, Prahasana, Dima, Vyayoga, Samavakara, Vithi, Anka, and Ihamriga.
Matching: B-III.
3. Uparupakani (Minor Dramatic Forms): There are exactly 18 minor types.
These include Natika, Trotaka, Goshthi, Sattaka, etc., which are shorter or more lyrical/musical than the Rupakas.
Matching: C-I.
4. Sandhayah (Dramatic Junctures): There are exactly 5 Sandhis.
These are: Mukha, Pratimukha, Garbha, Avamarsha, and Nirvahana. They represent the chronological stages of the plot development.
Matching: D-II.
By organizing these traditional counts, we get the sequence A-IV, B-III, C-I, D-II.
Step 4: Final Answer:
The standard counts in Natyashastra are Abhinaya (4), Rupaka (10), Uparupaka (18), and Sandhi (5). Thus, Option (B) is correct.
