How to get which list item is clicked in Javascript?

<StackPanel Padding="0,5,0,20">
  <Each Items="{data.options}">
      <Text TextWrapping="Wrap" Value="{option}" Padding="40,15,40,15" TextColor="#fff" FontSize="18" Font="gMedium" TextAlignment="Right" Alignment="VerticalCenter" />
        <Callback Handler="{optionClicked}"/>

In the above code when a list item is clicked optionClicked Handler is called. So in the optionsClicked Handler how to get which option is clicked?

args will include the relevant part of data.options so you can check there.
