(B) Array- It's size cannot be increased or decreased once it is declared.

(K) extends - A sub class extends super class.

(C) Private- is only visible within the class which it is declared.

(I) Concrete class- May have a object implementation of it.

(D) Protected- is only visible within the class or any sub-class of which it is declared.

(E) Public- is visible within the class it is declared and any other class in the program.
