Portfolio B has a higher dollar exposure to a change in stock price because it has more shares of stock. The call delta is a measure of how much the option's price will change for a given change in the stock price. In this case, the call delta is 0.3, which means that the option's price will increase by $0.30 for every $1 increase in the stock price. However, Portfolio A has more calls than shares, so it will have a higher exposure to changes in the option's price.
