Concept:
Jain philosophy explains liberation as freedom from karmic bondage.
For liberation, karmic influx must be stopped and accumulated karma must be destroyed.
Step 1: Start with Samvara.
Samvara means stopping the inflow of new karma.
So:
\[
D = \text{Samvara}
\]
Step 2: Next comes Nirjara.
Nirjara means shedding or destruction of accumulated karma.
So:
\[
C = \text{Nirjara}
\]
Step 3: Then comes Kevala Jnana.
When karmic obstructions are destroyed, the soul attains perfect knowledge.
So:
\[
B = \text{Kevala Jnana}
\]
Step 4: Finally comes Siddha-Shila.
The liberated soul rises to Siddha-Shila.
So:
\[
A = \text{Siddha-Shila}
\]
Thus, the correct order is:
\[
D \rightarrow C \rightarrow B \rightarrow A
\]
Hence:
\[
\boxed{\text{(A) D, C, B, A}}
\]
