Bell Corporation grants an incentive stock option to Peggy, an employee, on January 1, 2019, when the option price and FMV of the Bell stock is $80. The option entitles Peggy to buy 10 shares of Bell stock. Peggy exercises the option and acquires the stock on April 1, 2021, when the stock's FMV is $100.
