Step 1:
Consumer buying process begins when a consumer recognizes a problem or need.
\[
D = \text{First Step}
\]
Step 2:
After recognizing the need, consumer searches for relevant information.
\[
A = \text{Second Step}
\]
Step 3:
Consumer compares different available alternatives.
\[
C = \text{Third Step}
\]
Step 4:
Finally:
• Consumer makes purchase decision
• Experiences post-purchase satisfaction or dissatisfaction
Correct sequence:
\[
D,\; A,\; C,\; B,\; E
\]
Hence, the correct answer is:
\[
\boxed{\text{(2) D, A, C, B, E}}
\]
