Which of the following is NOT a type of non-infectious disease?

The correct choice is based on the understanding that non-infectious diseases are those that cannot be spread from one individual to another and generally have different origins compared to infectious diseases, which are caused by pathogenic organisms like bacteria, viruses, fungi, or parasites.

Congenital diseases result from genetic factors or development issues that occur before birth and are not caused by infections. Nutritional diseases stem from deficiencies, imbalances, or excesses of nutrients in the diet and also do not arise from infectious agents. Degenerative diseases are conditions that involve the gradual deterioration of tissues or organs over time, which again is unrelated to infection.

In contrast, infectious diseases are specifically defined as illnesses caused by pathogens that can be transmitted between individuals. This fundamental distinction makes it clear why infectious diseases do not belong in the category of non-infectious diseases.
