Right, D.

Is the first question true

It's false I think actually

To determine the correct answer to this question, we need to understand what categories of infectious diseases are being referred to. Here is an explanation of each option:

A. Chronic diseases such as heart disease or diabetes: Chronic diseases are long-term conditions that typically develop slowly over time and have various causes, including genetic, environmental, and behavioral factors. However, chronic diseases are not typically considered infectious diseases.

B. Degenerative diseases such as Alzheimer's disease: Degenerative diseases involve the progressive deterioration or loss of function in cells, tissues, or organs over time. They are not typically considered infectious diseases.

C. Genetic diseases such as cystic fibrosis: Genetic diseases are caused by abnormalities in an individual's genes or chromosomes and are typically inherited from one or both parents. Like chronic and degenerative diseases, genetic diseases are not typically considered infectious diseases.

D. Pandemics such as Ebola: A pandemic refers to the worldwide spread of a new infectious disease. Pandemics are a type of infectious disease outbreak that affects a large population across multiple countries or continents. While this option is related to infectious diseases, it does not explain the categories of infectious diseases.

E. All of the above: Since options A, B, and C do not accurately explain the categories of infectious diseases, this option is also incorrect.

Based on the explanations above, the best answer to the question would be D, which refers to pandemics such as Ebola.
