B, C and D are logically the same, the misuse of addr:place in example D 
is simply due to being literal in the use of addr:parentstreet instead 
of using it as "addr:parentlocalisation" (or whatever a better name 
would be).

So D should simply be

addr:housenumber = 3
addr:street = James Bennett Avenue
addr:parentlocalisation = Futura Park

That we have the addr:street / addr:place dichotomy instead of just one 
key for an addressing element with that semantic is due to how they 
historically evolved, it isn't really necessary*, and there is no reason 
to do the same thing with addr:parentwhatever.

Are the address elements, in particular the addr:street values actually 
formal postal addresses in this case?

Simon

* Switzerland has ~160'000 streets that turn up as street names in addresses, and ~40'000 non-street objects, that is farms, other named settlements etc. that are used at the same level of addressing hierarchy. All these values use the same field in the national address dataset STRNAME (STR from Strasse, Street), and nobody blinks an eye at the massive intellectual challenge of having to abstract things a bit.
