(Call strikes) Consider a family of European call options on a non-dividend- paying stock, each option being identical except for its strike price. The value of the call with strike price K is denoted by C(K). Prove the following two general relations using no-arbitrage arguments: (a) K2 > Ki implies K2 K > C(K1) C(K2). (b) K3 > K2 > Ki implies K3 - K2 K2 K (K2) C(K1) C(K3).
