Step 1: Understanding the Parvas.
The Mahābhārata is structured into 18 Parvas (sections or books).
The initial four Parvas are crucial for establishing the epic's narrative foundation.
Step 2: Parva Order.
- Ādiparva (D): Details the Kuru dynasty's origins and genealogies.
- Sabhāparva (A): Covers the assembly hall and the pivotal dice game.
- Vanaparva (C): Recounts the Pāṇḍavas' period of exile in the forest.
- Virāṭaparva (B): Describes the Pāṇḍavas' incognito period in Virāṭa's realm.
Step 3: Correct Sequence.
The correct chronological arrangement is: Ādiparva → Sabhāparva → Vanaparva → Virāṭaparva.
Step 4: Conclusion.
Therefore, the correct sequence is D, A, C, B.
