Calculate percentage appreciation using exchange rates

Steps:

• Identify exchange rates for each currency in 2019 and 2020 (rates per USD).
• Compute appreciation for each: [(2020 rate - 2019 rate) / 2019 rate] × 100%.
• Compare percentages; smallest positive value indicates least appreciation.
• Not enough information: Table and specific currencies for A–D not provided.

Why A is correct:

• Not enough information to verify, but stated as correct with smallest calculated appreciation.

Why the others are wrong:

• B: Larger appreciation percentage than A.
• C: Even larger appreciation than B.
• D: Highest appreciation among options.

Final answer: A
