What do visibility rules in a form accomplish?

Visibility rules in a form are utilized to dynamically show or hide fields based on the user's previous answers. This functionality enhances user experience by only displaying relevant fields, thus streamlining the form-filling process and reducing user frustration. For instance, if a user selects a certain option that necessitates additional information, visibility rules can reveal those specific fields. Conversely, if an option is selected that does not require additional details, the related fields can be hidden, ensuring that the form remains clean and user-friendly.

The other options do not accurately describe the purpose of visibility rules. Resetting form fields pertains to starting the form afresh, validating submissions focuses on ensuring the correctness of the entire input, and preventing submission relates to overall form errors rather than the dynamic showing or hiding of fields based on user input. Therefore, the primary function of visibility rules is to manage which fields are visible based on previous user interactions.
