Show/Hide Explanation
Correct Answer: C
Here, the scale of the x-axis is uniform. Hence, growth is greatest when the curve is steepest. The growth
curve of the US dollar against the Pak Rupee is the steepest (increased by a bit more than six horizontal
lines on the graph) on January 21. Hence, the answer is (C). On February 5th, the growth is the next
greatest, growing by a bit less than 6 horizontal lines.
