Step 1: Understanding the Concept:
A 'Sandhi' in dramaturgy is the juncture that connects the structural parts of the plot. There are five Sandhis that correspond to the five stages of action (Karyavasthas) and five elements of the plot (Artha-prakritis). A standard five-act Nataka must follow this specific sequence to achieve a logical and emotionally satisfying conclusion.
Step 3: Detailed Explanation:
The chronological order of Sandhis is:
1. A. Mukhasandhi (The Opening): Where the seed (Bija) of the plot is sown and the action begins (Arambha). It covers the exposition.
2. C. Pratimukhasandhi (The Progression): Where the seed grows and becomes visible, though it may occasionally be hidden. It corresponds to the 'Yatna' (Effort) stage.
3. D. Garbhasandhi (The Development): Where there is further growth and the goal seems near, but there is still some doubt or searching. It corresponds to 'Praptyasha' (Hope of achievement).
4. B. Vimarshasandhi (The Pause/Reflection): Where the goal is very close but is hindered by some new complication, anger, or temptation. It corresponds to 'Niyatapti' (Certainty of achievement, though obstructed).
5. E. Upasamhriti (The Conclusion/Nirvahana): Where all the threads of the story are brought together to achieve the final fruit (Phalayoga).
The sequence A, C, D, B, E is the invariant structure of a full Sanskrit drama. Each Sandhi has its own sub-divisions (Angas) that further define the dramatic movement.
Step 4: Final Answer:
The correct order is Mukha, Pratimukha, Garbha, Vimarsha, and Upasamhriti. Hence, Option (C) is the correct answer.
