I don't know which is correct, but they should do the same thing (possibly both erroring out).
> db.foo.find()
{ "_id" : ObjectId("4fff661614a4344a2507267c"), "a" : { "b" : { "c" : 1 } } }
{ "_id" : ObjectId("4fff73ad14a4344a2507267d"), "a" : [ { "b" : [ { "c" : 1 } ] } ] }
> db.foo.find({}, {'a':1, 'a.c':1})
{ "_id" : ObjectId("4fff661614a4344a2507267c"), "a" : { } }
{ "_id" : ObjectId("4fff73ad14a4344a2507267d"), "a" : [ { } ] }
