Which scenario defines a long call option's profit potential?

A long call option's profit potential is characterized by unlimited profit potential while having a fixed downside. When an investor buys a call option, they acquire the right, but not the obligation, to purchase an underlying asset at a predetermined strike price before the option expires.

In this scenario, the investor's upside is theoretically unlimited because, if the price of the underlying asset rises significantly above the strike price, the value of the call option increases correspondingly. The potential gain can continue to grow as the underlying asset's price increases without any higher limit.

On the downside, the maximum loss is strictly limited to the premium paid for the call option. If the option expires worthless because the underlying asset price does not exceed the strike price, the investor only loses the premium they paid. Therefore, the fixed downside in this context refers to the initial investment in the premium, while the profit opportunity remains open-ended and expansive as the price of the underlying asset increases.
