An app builder must stop a discount above 20 percent from being saved on a Quote. Which validation rule design is correct?

選択肢

1. A formula that returns true when the discount exceeds 20 percent, because the rule blocks the save whenever its formula evaluates to true.
2. A formula that returns true when the discount exceeds 20 percent, combined with the error condition setting switched from block to warn so that users can override it.
3. A formula that returns the discount percentage.
4. A formula that returns true when the discount is 20 percent or lower, because the rule describes the condition that a valid record must satisfy and the platform blocks the save when that condition is not met.
