MVC :: Write The Code Which Translates The Language Property Into A CSS Class?

I'm having problems drawing the lines on what code goes where in the following case. What goes in the View, Controller and Model. It should be noted that this is my first MVC project.So I'm building a bilingual site where the user may select either English or Norwegian language. I want the user to be able to choose language with a link at the top of the page. The link for the selected language at any time is emphasized with a certain CSS class.

The user setting with the selected language at any time is stored in a cookie at the client. When a request is done, the cookie is parsed and the settings are objectified as a part of the Model the way I've implemented it as of now (please object if you find this weird, but this is not the main focus of this post). I.e. a super-class which all my models inherit from, has the UserSettings class with the Language property.Now, where do I write the code which translates the language property into a CSS class?Option A, the View: I envision some code which interprets the language and output one of two possible lines of code based on this. We'll have IF's in the View.

Option B, the Controller: Logic in the Action method sets a ViewData-property with the name of the CSS class for both the link to the Norwegian and the English language.

Option C, the Model: I create a new property in the Model doing the same thing as the code in Option B. Except now I get strongly-typed parameters in the View and intellisense. (But I do suspect you guys will not like this solution for separation-of-concerns-reasons)

Option D, the ViewModel* I create a new class which is a ViewModel for the Model with the same property as in Option C. Now I get better separation of concerns.Yes I know there's no ViewModel in MVC, but I also know some people implement it anyway.

So what do you say? A,B,C or D? Or maybe you've got an E?
