Answer:
B. Euro appreciated against the dollar
Explanation:
Depreciated means a decrease in value. Therefore, option A is incorrect. Since the exchange rate of Euro increases, the dollar cannot be appreciated at the same time. So, C cannot be the answer. If "C" is incorrect, both "B" and "C"; it means "D" is incorrect.
Hence, option "B" is correct because the foreign exchange rate of Euro increases relative to the exchange rate of the dollar in 2002. If there is an increase of a currency relative to others, the increased currency is said to be appreciated.
