(B) The person has threatened to inflict serious bodily injury on himself or herself, and there is a reasonable probability that the conduct will occur if admission is not ordered; or

(C) The person's recent behavior or behavior history demonstrates that he or she so lacks the capacity to care for his or her own welfare that there is a reasonable probability of death, serious bodily injury, or serious physical or mental debilitation if admission is not ordered; or

(D)

(i) The person's understanding of the need for treatment is impaired to the point that he or she is unlikely to participate in treatment voluntarily;

(ii) The person needs mental health treatment on a continuing basis to prevent a relapse or harmful deterioration of his or her condition; and

(iii) The person's noncompliance with treatment has been a factor in the individual's placement in a psychiatric hospital, prison, or jail at least two (2) times within the last forty-eight (48) months or has been a factor in the individual's committing one (1) or more acts, attempts, or threats of serious violent behavior within the last forty-eight (48) months.
