To compute the value of a put using the Black-Scholes option pricing model, you: Multiple Choice first have to apply the put-call parity relationship. first have to compute the value of both N(-d1) and N(-d2). compute the value of an equivalent call and then subtract that value from one. compute the value of an equivalent call and then subtract that value from the market price of the stock. compute the value of an equivalent call and then multiply that value by e-RT
