9. Let S = \($40\), K = \($45\), σ = 0.30, r = 0.08, and δ = 0. Compute the value of knockout calls with a barrier of \($60\) and times to expiration of 1 month, 2 months, and so on, up to 1 year. As you increase time to expiration, what happens to the price of the knock-out call? What happens to the price of the knock-out call relative to the price of an otherwise identical standard call?
