The second statement made by Giana Greg is incorrect in the context of the put-call parity relationship. Put-call parity is a principle that defines a relationship between the price of a European call option and European put option, both having the same strike price and expiration date. The key point here is that the options must be European-style, not American-style. European-style options can only be exercised at expiration, which aligns with the maturity date of the discount bond in the put-call parity equation. American-style options, on the other hand, can be exercised at any time before expiration, which can disrupt the balance of the put-call parity relationship. Therefore, the assertion that the put-call parity relationship holds true for American-style options is inconsistent with the fundamental principles of put-call parity.\n\nChoice A is incorrect. Statement I is correct. The put-call parity relationship does indeed require the strike price and the time to maturity of the put and call options to be identical. This condition ensures that both options are comparable, thereby establishing a relationship between their prices.\n\nChoice C is incorrect. As explained above, statement I is correct, which means that not both statements are incorrect.
