The correct option is A Obiter dicta
Obiter dicta are remarks or observations made by a judge that, although included in the body of the court's opinion, do not form a necessary part of the court's decision. In a court opinion, obiter dicta include, but are not limited to, words "introduced by way of illustration, or analogy or argument". Obiter dicta are not the subject of the judicial decision, even if they happen to be correct statements of law.
