17) b) Rate of retun on underlying asset
18) e) The value of american put will be equal or exceedthe value of comparable european put
Since in american options , one can exercise the option whenever it is favourable it's value will always be high or equal to european options
19) b) European options but not American options
Black Scholes is used to find value of european options only
20) a) III and IV only
Formula for call option = So*N(d1) - Xe^-rt *N(d2)
Formula for put option=Xe^-rt *N(-d2) - So*N(-d1)
Here X=strike price and So = stock price
21) Delta value of call option always ranges from 0 to 1 because as underlying asset increases in price call option increases in price
Thus ans a) between zero and one
