(a) A long call option's payoff at maturity is equal to the maximum of zero or the underlying asset price at maturity minus the exercise price. ##f_\text{T,LC} = max(S_T - K, 0)##

(b) A long call option's profit is equal to the payoff at maturity less the initial option price. ##\pi_\text{LC} = max(S_T - K, 0) - c_0##

(c) The breakeven price is the underlying asset price at which a long option contract gives zero profit. When ##max(S_T - K, 0) - c_0 = 0##, then ##S_T = K+c_0##.

(d) A call option's break-even price is always more than its strike price.

(e) Call options should only be exercised at maturity if the underlying asset price is above the break-even price.

(a) All people would appear rational to an economist since they prefer more wealth to less.
