Which option is NOT a characteristic of good electronic forms design?

Using radio buttons for multiple selections is not a characteristic of good electronic forms design because radio buttons are designed for single selection from a set of options. When users need to select more than one option, checkboxes are the appropriate choice. Good electronic form design aims to minimize confusion and streamline the data entry process, ensuring that users can make their selections easily and accurately.

In contrast, minimizing keystrokes with pop-up menus, checking the completeness of required data, and using text boxes for data entry are all characteristics of effective form design. Pop-up menus can help in reducing typing effort by providing users with a list of options to choose from, thereby decreasing the chances of errors. Checking the completeness of required data ensures that all necessary information is captured before submission, which is crucial for data integrity. Text boxes offer users the flexibility to enter various types of data, making the form adaptable to different input needs.
