Step 1:
DAGMAR stands for:
\[
\text{Defining Advertising Goals for Measured Advertising Results}
\]
It explains stages through which a consumer moves before purchasing.
Step 2:
The consumer first remains:
\[
\text{Unaware}
\]
Then becomes:
\[
\text{Aware}
\]
Thus:
\[
D \rightarrow C
\]
Step 3:
After awareness:
• Consumer develops comprehension and image
• Then develops attitude toward product
Thus:
\[
E \rightarrow A
\]
Step 4:
Finally, the consumer takes purchase action.
Correct sequence:
\[
D,\; C,\; E,\; A,\; B
\]
Hence, the correct answer is:
\[
\boxed{\text{(3) D, C, E, A, B}}
\]
