Answer (C) is correct . For European options, given market equilibrium for all relevant prices (no arbitrage possibilities), equal exercise prices for the put and the call, and the same expiration date, the put-call parity theorem states that a fixed relationship applies to the market values of the put and call options on a security. For example, a strategy of selling one call option, buying one share of the stock, and buying one put option should result in a risk-free return. The gain (loss) from the stock and the put should equal the gain (loss) on the call. If V S is the value of the stock, V P is the value of the put, V C is the value of the call, and PV E is the present value of the exercise price (the time interval is the time to expiration), the formula for put-call parity may be stated as follows: Accordingly, the value of the put is $.50 ($36 + $4.50 – $40).

Answer (A) is incorrect because The amount of $4.50 is the value of the call.
Answer (B) is incorrect because The amount of $4.00 is the difference between the exercise price and its present value.
Answer (D) is incorrect because The put has a value of $.50.
