Haha, I bet the person who wrote this question was picturing a status bar the color of a traffic light. Option C is the way to go.

C) The color for the status bar. If the color is not opaque, consider setting View.SYSTEM_UI_FLAG_LAYOUT_STABLE and View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN. For this to take effect, the window must be drawing the system bar backgrounds with R.attr.windowDrawsSystemBarBackgrounds and the status bar must not have been requested to be translucent with R.attr.windowTranslucentStatus. Corresponds to Window.setStatusBarColor(int).
