b. The basket could be purchased in Britain for £200 and sold in the United States for $200, and the $200 could be used to buy £200, for a £500 profit.
c. The basket could be purchased in the United States for $400 and sold in Britain for £400, and the £400 could be used to buy $1,400, for a £1,000 profit.
d. The basket could be purchased in the United States for $200 and sold in Britain for £400, and the £400 could be used to buy $800, for a $400 profit.
