Unless you have generated strongly typed classes, looking up Optionset values for the selected value or any other value, is one of the most annoying things to do as a developer. You can use the bookmarklet below to display Optionset values, along with the Optionset text for all the Optionsets on a form. You can drag the minified source to your bookmark bar, for creating the bookmarklet.
This is how a sample contact form looks after executing the bookmarklet.
