Microsoft Forms Quiz

@Jon_Kay 

Thank you for your quick response sir.

 But sir I am not talking about checkbox... I am talking about Radio Button. only one answer selection. 

I will tell what happened yesterday in my class....

I conducted the assessment using Form Quiz. Attached here photo.

Students attempted an assessment and they submitted the res responses. But after submitting, 15 -17 learners started complaining that ma'am I selected correct option but after submitting it is showing another option that we didn't selected.. Is this possible in Quiz? Can you guide me.
