People, better if you write explanation WHY it is E instead of giving the same answer multiple times.
E is correct
if a non-static method is overrided by a subclass
then JAVA will use this overrided method , no mmater what Type this object is declared
but for the variable and static method , which target should be used depend on the Type
object type and reference type are different things, just look at the object creation – “new” keyword – once object is created it doesn’t change – casting it to superclass later is only changing reference type
