MVC :: How To Get Access To The Fields In Table B In The View

I do not know if this can be done but lets say have a model like the one below:

I am trying to do this:

<%= Html.RadioButtonFor(model => model.B.height)%> -----> Does not work. Height is not a property

But B is a collection. How do I get access to the fields in table B in the View?
