Step 1:
These are Sanskrit nominal case endings arranged systematically.
Step 2:
The order begins with:
\[
Su,\; Au,\; Jas
\]
followed by:
\[
Am,\; Aut,\; Śas
\]
Step 3:
Then come:
\[
Tā,\; Bhyam,\; Bhis
\]
followed by the remaining endings.
Step 4:
Thus, the correct order is:
\[
C \rightarrow B \rightarrow A \rightarrow D \rightarrow E
\]
Hence, the correct answer is:
\[
\boxed{\text{(4)}}
\]
