The correct answer is C — Accidental injury. An accidental injury results from an unintended or unforeseen event producing bodily harm. This characteristic distinguishes an accident from deliberate conduct or an intentionally produced injury. New York's accident-insurance framework treats accident coverage as insurance for death, dismemberment, disability, medical care, or similar loss caused by an accident or specified types of accidents. DFS also requires accident-only policies to make clear that benefits relate to a covered accident, rather than sickness generally.

Options B and D involve intentional self-harm and therefore do not satisfy the ordinary accidental-event concept stated in the question. A suicide attempt is intentionally undertaken even though the eventual degree of injury may not have been intended. A deliberate self-inflicted injury is expressly intentional by definition.

Alcohol abuse is also not itself an unforeseen accidental act producing bodily injury. Although an accident might occur while a person is intoxicated, the abuse itself is not synonymous with an accidental injury and coverage would depend on the actual policy wording and circumstances.

For examination purposes, the defining characteristics are unexpectedness, lack of intent, and resulting bodily harm.
