Concept:
Exchange rate terms describe changes in the value of currencies under fixed or floating exchange systems.
Step 1:
Appreciation means a currency increases in value under a floating exchange rate system.
\[
A \rightarrow I
\]
Step 2:
Devaluation means the government officially reduces the value of currency in a fixed exchange rate system.
\[
B \rightarrow II
\]
Step 3:
Depreciation means the value of a currency decreases naturally in a floating exchange system.
\[
C \rightarrow III
\]
Step 4:
Revaluation means officially increasing the value of a currency in a fixed exchange system.
\[
D \rightarrow IV
\]
Step 5:
Thus, the correct arrangement is:
\[
A-I,\ B-II,\ C-III,\ D-IV
\]
\[
\boxed{\text{(1) A-I, B-II, C-III, D-IV}}
\]
