Final answer:
The American put option on stock XYZ is in the money because its strike price is higher than the stock's current trading price. The intrinsic value of the option is $8, but it is trading at $10. Therefore, immediate exercise for arbitrage is not profitable as the option's cost exceeds its intrinsic value.
Step-by-step explanation:
The correct statement about the American put option on stock XYZ with a strike price of $48 is that the put is in the money. This means that the current price of the stock ($40) is lower than the strike price of the put option ($48). Therefore, the option has intrinsic value, which is the difference between the strike price and the stock price, amounting to $8 ($48 - $40). The put option is trading at $10, which is $2 above its intrinsic value, accounting for time value and other factors. Exercising the put option immediately for arbitrage profit would not be viable since the cost of the put ($10) is higher than the intrinsic value ($8).
