What does 25% delta mean option?

Could you please clarify what you mean by "25% delta mean option"? Are you referring to the concept of delta in options trading, specifically the relationship between the change in the price of an underlying asset and the change in the price of an option on that asset? If so, a 25% delta on an option would suggest that for every 1% change in the price of the underlying asset, the option price would be expected to change by approximately 0.25% in the same direction. Is this what you were asking about, or did you have something else in mind?
