the default one (option 3) is false because: "all the building subclasses(hotel, hospital) are covered, except for "null" case, so we need null, not default" is that true?

No, did you read the explanation?
This is syntactically valid but does not implement the logic given in the problem statement. If b is null, this code will throw a NullPointerException while the code in the problem statement will not.
So default will work but not exactly as the logic given in the problem statement.
