While your code formatting leaves much to be desired, to check/uncheck has a lot of priors at https://www.google.com/search?q=uncheck+radio+button+in+c%23

All those blank lines are distracting and have me scroll up and down so I'll ask you try harder on the formatting.

The radiobutton Checked property can be set to true or false in your program.

is there anyother way to match answers ?

[ddanbe]

Yes, perhaps something like this:

A question
1.answer 1
2.answer 2
3.answer 3

Then in a textbox let the user answer 1,2 or 3, process this answer further.
