Which of the following is NOT a type of hazard?

The correct choice is C, Environmental. In the context of risk management and insurance, hazards are classified into three primary types: physical, moral, and morale.

Physical hazards involve tangible conditions or objects that increase the likelihood of loss or injury, such as faulty wiring or slippery floors. Moral hazards are related to the attitudes and behaviors of individuals that may lead to increased risks, such as dishonesty or intent to cause harm for financial gain. Morale hazards reflect an individual's attitude towards risk, demonstrating a lack of concern for potential loss, which can lead to reckless behavior.

Environmental hazards, however, do not fit into the traditional classifications of hazards within insurance and risk management frameworks. While environmental factors can contribute to loss events, such as natural disasters, the term "environmental hazard" is broader and not recognized as one of the specific types of hazards that influence insurable risks in the same systematic way as physical, moral, and morale hazards do. Therefore, it stands apart from these categories in the context of this question.
