Coming at this from a non-theoretical perspective, I'd say that choice c
is the one that makes intuitive sense, and the one that is easy to
explain (say, if one were writing a book about this language). If
safety and theoretical concerns don't dictate a choice, I'd argue that
common sense suggests c.
