Which feature helps to ensure that users provide valid data before submitting forms?

Field validation options are essential in ensuring that users provide valid data before submitting forms. This feature allows developers to set specific rules and criteria for each input field within a form. For example, it can check that an email address is correctly formatted, that numbers fall within a specified range, or that required fields are not left empty. By implementing these validation rules, the system can prevent incorrect or incomplete data from entering the system, thus maintaining data integrity and enhancing the user experience by providing immediate feedback.

Other features such as help tips, default values, and field arrangements enhance user experience but do not inherently prevent invalid data entry. Help tips offer guidance but do not enforce data accuracy. Default values can help streamline form completion but do not guarantee that the data entered aligns with required formats or constraints. Finally, while field arrangement improves usability and aesthetics, it does not validate the information users provide.
