Step 1:
A brand name is the name assigned to a specific product.
Thus:
\[
A \rightarrow I
\]
Step 2:
Trade name refers to the name of the company or business organization.
Thus:
\[
B \rightarrow III
\]
Step 3:
• Brand equity $\rightarrow$ Value associated with brand
• Slogan $\rightarrow$ Short promotional phrase
Thus:
\[
C \rightarrow IV
\]
\[
D \rightarrow II
\]
Step 4:
Final matching:
\[
A-I,\; B-III,\; C-IV,\; D-II
\]
Hence, the correct answer is:
\[
\boxed{\text{(1) A-I, B-III, C-IV, D-II}}
\]
