Answer:
B. The price of the call option will increase by less than $2, but the percentage increase in price will be more than 10%.
Step-by-step explanation:
Given
Trading price = $20
Exercise price of call option = $20
Call option price = $1.50
Price increment = 10% to $22
It's not be noted that the discounted present value of a price of an option is represented by its expected payoff.
An increment of $2 in stock price attracts an increment of more than $2 in the payoff option.
Having highlighted that, it's also to be noted that the increment in expected payoff will be by an amount less than $2 and same with present value because the possibility is less than 1. So, the price of the option will increase by less than $2.
Moving to the percentage increase;
This will be larger than 10%.
This is because when stock price increases by 10%, the value of the option will increase by more than 10%.
