Answer: b. 34.15 or higher
Step-by-step explanation:
Short sales refer to the sale of borrowed stocks in anticipation that the stock price of the underlying stock will fall. This will then enable you to make a profit by buying the cheaper shares and giving it back to the entity you borrowed from thereby making a profit.
With short sales, the price is usually upward trending so will normally increase from the last price. As the last price here was $34.15, that would be the likely minimum for the next sale.
This means that the next sale will either be at a price of $34.15 or a price higher than that.
