B: h_1=uicontrol(gcf,'style','push', 'string','grid off','callback','grid off');
C: h_1=uicontrol(gcf,'style','text', 'horizontal','left','string',{'Input'});
D: h_1=axes('unit','normalized','position',[0,0,1,1],'visible','off');
A: h_1=uimenu(gcf,'Label','&Blue');
B: h_1=uicontrol(gcf,'style','push', 'string','grid off','callback','grid off');
C: h_1=uicontrol(gcf,'style','text', 'horizontal','left','string',{'Input'});
