Binomial Model Call Option Valuation

Jane is evaluating a European call option on a stock with a current price of $50. She decides to apply a one-period binomial model to assess the option's value. In this model, the stock can move up to $60 or down to $40 at expiry. The risk-free rate is 5% per annum. Jane wishes to calculate the present value of the call option. What is the correct price of the European call option?
