Unpopulate Google Form by default

I made a survey in Google Forms. It consists of several multiple-choice questions. When I preview the form or use the link I would send to participants, some of the answers are already populated/preselected.

Because I – logically – do not want to suggest a particular answer, nor give participants the idea they already answered a question, I am wondering: is there any way to have all questions be unpopulated by default (or somehow deselect these preselected answers)?
