Yes indeed just like a dog with a bone!!

48 = DBA_SEGMENTS
63 = SYS and INTERNAL (not SYSTEM)
61 = this looks like they are asking about tablespace segment size and not physical size. So, if that is the case then INITIAL would be the answer. Somewhat misleading question there, but I would say that A might be the MOST correct answer? anyone have any suggestions on this one?

hi
i think initial size of the tablespace depends on the size of datafiles created during tablespace creation, would go with E.
