lol, I was about to say this is a rookie error, then I realized you on the wrong website altogether.   

This is a Revit API forum.

how some one can fail so much, maybe life of programmer is just not for you.
btw you made typo here

options.Add(options);

 but you probably will not read this just like you didn't read a exception description, debug info in unity, name of the forum and probably your own code.

This is actually a very simple error that is easy to make (the error in the code that is). In your for loop you typed options.Add(options); instead of options.Add(option);.
