Assume that a stock is currently selling at a price of $75.00 in the open market. A put, with an exercise price of $77.00, sells for $2.00.

Assume that a share of stock has a current price of $60. Also assume that a call option on this stock has 1 year to maturity, a standard deviation of 0.20, an exercise price of $50, and that the appropriate 1-year interest rate is 4.00%. What is the price of this call option using the Black-Scholes option-pricing model? (A cumulative normal probability table is at the end of this exam -- you should round off your answers for d 1 and d 2 to two decimal places.) A. $12.04 B. $13.75 C. $14.19...
