Step 1:
Monopolistic competition combines features of monopoly and perfect competition.
Step 2:
Important features are:
• Large number of buyers and sellers
• Product differentiation
• Free entry and exit
• Selling costs like advertisement
Step 3:
Homogeneous products are a feature of perfect competition, not monopolistic competition.
Thus:
\[
D = \text{Incorrect}
\]
Step 4:
Correct features are:
\[
A,\; B,\; C,\; E
\]
Hence, the correct answer is:
\[
\boxed{\text{(1) A, B, C and E only}}
\]
