Data hiding, which means that critical data stored inside the object is protected from code outside the object, is accomplished in Java by:
A) using the public access specifier on the class methods
B) using the private access specifier on the class methods
C) using the private access specifier on the class definition
D) using the private access specifier on the class fields

Data hiding is achieved by using the private access specifier on the class fields, which makes them inaccessible to code outside the object. Using public access specifier on class methods would make them accessible to code outside the object, which could potentially compromise the data hiding. Similarly, using the private access specifier on the class definition would not provide any data hiding, as it only affects the visibility of the class itself, not its fields or methods.
