Answer: Both a short forward position and a short call option position

**Explanation:** **Short Forward Position:** - A short forward position means you have agreed to sell the underlying asset at a predetermined price (forward price) at a future date. - If the price of the underlying decreases below the forward price, you can buy the asset at the lower market price and sell it at the higher forward price, resulting in a gain. - Therefore, a short forward position gains when the underlying price decreases. **Short Call Option Position:** - A short call option position means you have sold (written) a call option, giving the buyer the right to buy the underlying from you at the strike price. - When you sell a call option, you receive a premium upfront. - If the price of the underlying decreases, the call option becomes less likely to be exercised (since the buyer wouldn't want to buy at a strike price higher than the market price). - The option may expire worthless, allowing you to keep the entire premium as profit. - Therefore, a short call option position also gains when the underlying price decreases. **Conclusion:** Both positions benefit from a decrease in the underlying asset's price, making option C the correct answer.
