An acknowledgement checkbox.
This question type is commonly used for documenting that the responder has read the terms and conditions or is acknowledging the information presented in the page.
You can personalize the text that shows up next to the checkbox by editing the Confirmation text field in the setting menu that appears when the question is selected.
If you enable the Default to be checked option in the setting menu, the confirmation box will appear in its checked state when the content is first loaded.
In order to style the confirmation box (changing the padding between the text and the box or the color), you can style Multiple Choice (and not the radio buttons) boxes checkmarks menu.
