Step 1:
Planning starts with determining organizational objectives.
\[
B = \text{First Step}
\]
Step 2:
Planning premises include assumptions and forecasts about future conditions.
\[
A = \text{Second Step}
\]
Step 3:
Different alternative courses of action are identified and evaluated.
\[
D = \text{Third Step}
\]
Step 4:
The best plan is selected and supporting derivative plans are prepared.
Final sequence:
\[
B,\; A,\; D,\; C,\; E
\]
Hence, the correct answer is:
\[
\boxed{\text{(2) B, A, D, C, E}}
\]
