Which is a valid way to display data from a query on a form?

Using a dropdown component is a valid way to display data from a query on a form because dropdowns are specifically designed for scenarios where a selection needs to be made from a predefined list of options. This is particularly useful when the data retrieved from a query includes a finite number of relevant entries, such as options for categories, values, or statuses that a user might need to select from. By utilizing a dropdown, users can easily see all available choices without cluttering the interface, as the dropdown contains the options in a compact form until the user interacts with it.

In contrast, other options like checkboxes and text boxes serve different purposes. Checkboxes are typically used for binary choices or lists where users can select multiple items, which doesn't align well with a straightforward display of query results. A text box is mainly for user input and would not effectively convey a selection from queries but could serve as a display area for static text. Lastly, a date picker is specifically designed for selecting dates and would not be appropriate for representing a list of data retrieved from a query. Thus, the dropdown component stands out as the most suitable choice for displaying query data in a user-friendly manner.
