What is the primary purpose of a call option?

A call option serves as a financial contract that provides the buyer with the right, but not the obligation, to purchase a specified underlying asset at a predetermined price, known as the strike price, within a specified time period. This flexibility is a defining feature of call options, allowing the buyer to benefit from potential price increases in the underlying asset without committing to the purchase unless it proves advantageous.

The correct understanding of a call option emphasizes its nature of granting rights rather than imposing obligations, which is why the option that states it provides the right to purchase at a specified price is accurate. By holding a call option, a buyer can capitalize on upward price movements while retaining the option to withdraw from the transaction if market conditions are unfavorable.

In contrast, other choices do not align with the nature of call options. There is no obligation for the buyer to execute the option; rather, it is the right that is acquired. Additionally, the mention of selling rights pertains to put options, which focus on the sale of an underlying asset, rather than call options, which are concerned with purchasing.
