The correct answer is A.
The graph attached represents the supply and demand curves for Swiss francs. The amount of francs supplied and demanded is represented in the X axis while the price of francs (expressed in US dollars) is represented in the Y axis.
After the supply curve shifts right, it will intersect the demand curve, which stays the same, in a point on the right and below the initial intersection point. Therefore the quantity of francs exchanged in the new equilibrum will increase while the price charged for francs will decrease.
