C. ['Jan', 'Feb', 'Mar']
D. [('Jan', 'Feb', 'Mar')]

Hi

I would go for A, although I do not know what the \ means at the end.
Is it a typo maybe?

It's always been possible to use a subset (which is to say, a collection of some or all of the elements that make up a dimension) in Rules using curly braces, as discussed here. However named subsets are not supported in rules since it would then be impossible to predict what the outcome would be since anyone with admin access (or the ability to run a metadata-altering TI) could easily change (or worse, delete) the named subset definition and cause the values to change for everyone else.

And I agree with Wim, I believe that the backslash is a typo.

Thanks, Wim, Alan.
The only thing that confused me was the backslash. Finally it is placed next to the end square bracket.

In the TM1 Rules Editor, the syntax with backslash evaluates to an error, so I'm certain it must be a typo.
