I'm not familiar with WP8 programming as such but, based on my knowledge of WPF, I'd guess that your getSelectedAnswer method should be coded as follows:\
string getSelectedAnswer(){ if (radA.IsChecked) // IsChecked rather than Checked return radA.Content.ToString(); // Content rather than Text if (radB.IsChecked) return radB.Content.ToString(); if (radC.IsChecked) return radC.Content.ToString(); if (radD.IsChecked) return radD.Content.ToString(); return "";}
