Q12. What is the similarity and difference between option button and check boxes?
Ans. An option button is used to display an option that can be turned on or off. Usually option buttons are used for a group of options where from user can select just one.
Check boxes are used to allow a user select multiple choices.
Though option button and check boxes appear to function similarly, yet there is an important difference. When an option button is selected, all other option button controls in its group (i.e., in the same group) are automatically unselected. On the other hand, any number of check box controls can be selected.
