Concept:
Communication is the process of transferring information from one person or source to another receiver through a channel.
Step 1: Source.
Communication begins with the source.
\[
\text{First step}=A
\]
Step 2: Message.
The source prepares the message.
\[
\text{Second step}=D
\]
Step 3: Channel.
The message is sent through a channel.
\[
\text{Third step}=E
\]
Step 4: Receiver.
The receiver receives and interprets the message.
\[
\text{Fourth step}=C
\]
Step 5: Effect.
Finally, communication produces an effect or response.
\[
\text{Fifth step}=B
\]
Thus, the sequence is:
\[
A,D,E,C,B
\]
\[
\therefore \text{Correct Answer is (A)}
\]
