What are the four factors that determine the value of a call option according to the chapter on Enterprise Risk Management?

The four factors that determine the value of a call option are: the stock price, the exercise price, the time to expiration, and the risk-free rate.

The value of a call option is influenced by four main factors: 1) The stock price (S0) - a higher stock price increases the call's value. 2) The exercise price (E) - a higher exercise price decreases the call's value. 3) The time to expiration (t) - a longer time to expiration increases the call's value. 4) The risk-free rate (Rf) - a higher risk-free rate increases the call's value because it reduces the present value of the exercise price.
