Solution

1.The difference between check boxes and radio buttons :-

* When Radio Buttons are grouped they allow us to select one Radio Button at a time.

* When Check Boxes are grouped they allow us to select multiple Check Boxes at a time.

Explanation :-

Do not take single Radio Button. Because once Radio Button is selected we can not dis-select it. we always take multiple Radio Buttons together in a group.
