Explain Given: public class Triangle{ public int base; public int height; public double area; public Triangle(int base, int height){ = base; = height; updateArea(); } void updateArea(){ area = base*height/2; } public void setBase(int b){ base = b; updateArea(); } public void setHeight(int h){ height = h; updateArea(); } } The above class needs to protect an invariant on the "area" field. Which three members must have the public access modifiers removed to ensure that the invariant is maintained?This type of question contains radio buttons and checkboxes for selection of options. Use Tab for navigation and Enter or space to select the option. A option A the base field B option B the height field C option C the area field D option D the Triangle constructor E option E the setBase method F option F the setHeight method?
