A) var levelUp = prevLevel - headLevel; for (var i = 1; i outlineList = outlineList.parentNode.parentNode; }
B) var levelUp = prevLevel - headLevel; for (var i = 0; i >= levelUp; i++) { outlineList = outlineList.parentNode; }
C) var levelUp = prevLevel + headLevel; for (var i = 1; i >= levelUp; i++) { outlineList = parentNode.outlineList.parentNode; }
D) var levelUp = prevLevel - headLevel; for (var i = 0; i >= levelUp; i++) { outlineList = parentNode.outlineList.parentNode; }
