How do I assign Content of a Checked Radio-button in WPF to a property in ViewsModel

Hi,@Oladapo Kolawole Osagie . Welcome Microsoft Q&A.

For binding the value of the selected RaidoButton to the property, you could try referring to the code below.
Xaml:

<Window.Resources>  
        <ObjectDataProvider x:Key="selectOptions" ObjectType="{x:Type local:MyQuestion}" />  
        <local:RadioButtonCheckedConverter x:Key="RadioButtonCheckedConverter"  />  
    </Window.Resources>  
    <StackPanel>  
        <ListView Name="lv"  Background="AliceBlue"  ItemsSource="{Binding AllQuestions}" SelectedItem="{Binding SelectedQuestion}" SelectionChanged="ListView_SelectionChanged">  
            <ListView.ItemTemplate>  
                <DataTemplate>  
                    <StackPanel Background="LightPink" >  
                        <StackPanel Orientation="Horizontal">  
                            <TextBlock Text="{Binding Id}" FontSize="24"/>  
                            <TextBlock FontSize="20" Text="{Binding Question}"/>  
                        </StackPanel>  
                        <StackPanel Margin="40,0" >  
                            <RadioButton GroupName="{Binding Id}" FontSize="16" Content="{Binding OptionA}"   IsChecked="{Binding SelectedAnswer ,Converter= {StaticResource RadioButtonCheckedConverter}, ConverterParameter={x:Static local:Options.OptionA}}"/>  
                            <RadioButton GroupName="{Binding Id}" FontSize="16" Content="{Binding OptionB}"    IsChecked="{Binding SelectedAnswer ,Converter= {StaticResource RadioButtonCheckedConverter}, ConverterParameter={x:Static local:Options.OptionB}}" />  
                            <RadioButton GroupName="{Binding Id}" FontSize="16" Content="{Binding OptionC}"    IsChecked="{Binding SelectedAnswer ,Converter= {StaticResource RadioButtonCheckedConverter}, ConverterParameter={x:Static local:Options.OptionC}}"/>  
                            <RadioButton GroupName="{Binding Id}" FontSize="16" Content="{Binding OptionD}"   IsChecked="{Binding SelectedAnswer ,Converter= {StaticResource RadioButtonCheckedConverter}, ConverterParameter={x:Static local:Options.OptionD}}"/>  
                        </StackPanel>  
                    </StackPanel>  
                </DataTemplate>  
            </ListView.ItemTemplate>  

        </ListView>  
        <TextBlock x:Name="tb" Text="{Binding ElementName=lv ,Path=SelectedItem.SelectedAnswer , UpdateSourceTrigger=PropertyChanged}" Height="50" Background="LightGreen" />  
    </StackPanel>
