JS/Javascript - How to clear a matrix table answers when a check box is clicked

I believe checkbox is missing from your screenshot and for such checkbox you will have to use side by side question type.
Additionally you can do your usecase via custom coding.
Hope it helps!

The checkbox in the screenshot is the button at the bottom labeled "Preferred not to share"

Thank you for the clarification. You can include the below code in the multiple-choice question Javascript section.
Qualtrics.SurveyEngine.addOnReady(function()
{
/*Place your JavaScript here to run when the page is fully displayed*/
var qid= this.questionId;
jQuery('#'+qid).change(function(){
var values = jQuery('#'+qid+'-1-label')[0].attributes.class.value;
if(values=='MultipleAnswer  ChoiceTextPositionLeft q-checked'){
var n= jQuery('td').find('input').length;
for(let i=0;i jQuery('td').find('input')[i].value = '';
}
}
});
});
Hope it helps!
