> > Question 6 (12 marks) a) About a specific European call option on a non-dividend paying stock, we know the following: current stock price S. = 30, strike price K = 28, risk-free rate r=10%, and maturity at T=0.5. In addition, we observed this call option now has market value c =3.81. Suppose the volatility can only take two possible values: 20% or 30%. By using the BSM formula, find which one of them is the volatility of the underlying stock. Show calculations.
