Consider the 1-step Binomial model with r = 0.02, T = 2, So = 80, u = 1.2, d = 0.8, and pu= Pd = 0.5. (i) At time 0, the price of a European Call option with maturity T = 2 and strike K = 80 is Co 80 is Co= 8: find an arbitrage, or show that none exists. (ii) At time 0, the price of a European Put option with maturity T = 2 and strike K = 80 is Po 8: find an arbitrage, or show that none exists. =
