According to a Wall Street Journal article from the period: "The relentless strength of the franc has already pushed some weaker Swiss exporters into bankruptcy, and sent others scrambling to slash prices to hold onto business. Tourists, an important source of income for the Swiss economy, are now finding it more expensive than ever." To help its export/tourist sector, how would the Swiss National Bank intervene in the FX market? [Hint: keep in mind what an increase or decrease in the SFr/ exchange rate means for which currency is strengthening or weakening].

B. Sell Swiss francs for euros, causing an increase in the supply of Swiss francs and a decrease in the exchange rate.

C. Sell euros for Swiss francs, causing an increase in the supply of euros and a decrease in the exchange rate.

D. Sell euros for Swiss francs, causing an increase in the demand for Swiss francs and an increase in the exchange rate.
