Consider a European call option on a non-dividend-paying stock; when the option is written, the stock price is S_o, the volatility of the stock price is , the strike price is K, the continuously compounded risk-free rate is r, and the term to exipration is T; let c be the price of the option. The Black-Scholes formula for the option price is (select one)

A. c = S_oN(d₁) + Ke^-rTN(d₂) B. c = S_oN(d₁) - Ke^rTN(d₂) C. c = S_oN(d₁) - Ke^-rTN(d₂) D. c = S_oN(d₂) - Ke^-rTN(d₁)

where N(x) is the cumulative probability distribution function for a standardized normal distribution and d₁ and d₂ are parameters dependant on the structure of the option, the level of interest rates, and the volatility of the stock price.

	A.	c = SoN(d1) + Ke-rTN(d2)
	B.	c = SoN(d1) - KerTN(d2)
	C.	c = SoN(d1) - Ke-rTN(d2)
	D.	c = SoN(d2) - Ke-rTN(d1)
