Do you mean as a select or as a match pattern?  As a select, child::A is
single-level and child::B has stays-in-subtree; taken together,
child::A/child::B is single-level and child::C has stays-in-subtree.

So it seems to me that the compound expression meets the criteria for (b).

As a match pattern, nothing can be assumed to be single-level unless it's
anchored at the root.
