Concept:
The Sarvāstivāda school developed an extensive Abhidharma tradition consisting of seven foundational treatises. These texts systematized Buddhist psychology, ontology, cosmology, and epistemology. Each text became associated with a major Buddhist scholar or elder.
Step 1: Matching Jñānaprasthāna.
The Jñānaprasthāna is considered the central text or “body” (Śarīra) of the Sarvāstivāda Abhidharma system.
It was composed by:
\[
Kātyāyanīputra
\]
Hence:
\[
A \rightarrow III
\]
Step 2: Matching Vijñānakāya.
The Vijñānakāya deals with analysis of consciousness and cognitive processes.
Its traditional author is:
\[
Devaśarmā
\]
Hence:
\[
B \rightarrow IV
\]
Step 3: Matching Prakaraṇapāda.
The Prakaraṇapāda is an important systematic exposition of Buddhist categories and dharmas.
It is attributed to:
\[
Vasumitra
\]
Hence:
\[
C \rightarrow II
\]
Step 4: Matching Prajñāptisāstra.
The Prajñāptisāstra discusses conceptual designation and cosmological categories.
It is associated with:
\[
Maudgalyayana
\]
Hence:
\[
D \rightarrow I
\]
Step 5: Final Conclusion.
The final matching becomes:
\[
A-III,\quad B-IV,\quad C-II,\quad D-I
\]
Therefore, the correct option is:
\[
\boxed{(2)}
\]
