Haha, I bet the developers at Pentaho were having a laugh when they came up with these options. I'm going to go with option B, but I'm also going to carry a bag of '@' symbols with me just in case.
Option C with the '$' sign seems a bit unusual to me. I'm more familiar with the '@' symbol being used for variables, so I'm going to go with option B.
I was leaning towards option D, but the question specifically mentions 'free form text fields', so I'm not sure if that would apply to variables entered in all caps.

I think option B makes the most sense. The '@' sign is commonly used to denote variables in various programming languages, so it seems logical that it would be used in Pentaho as well.
