Which of the following is not a ‘fact’?

Section 3 of the Indian Evidence Act, 1872 defines 'fact' to include: (1) physical facts (state of things), (2) mental facts (mental condition), and (3) relations between things. All three categories listed in options A, B, and C are therefore 'facts' under the Act. Option D is correct because all the given options ARE facts - there is no non-fact among them. The question's phrasing requires selecting the option that acknowledges all are facts.
