In a 1-period binomial model, with initial stock price 100, if the stock price is either 50,100, or 150 after 1 period then how can I show there is no longer a unique no-arbitrage price for a European call option with strike price K=150. What would the range of values for this price be that ensure there is no arbitrage?
