  Underweight (BMI < 18.5)
- B.
  
  Normal Weight (BMI 18.5-24.9)
- C.
  
  Overweight (BMI 25-29.9)

- E.
  
  Moderately/Extremely Obese (BMI >= 35)
Correct Answer
A. Underweight (BMI < 18.5)

Explanation
Underweight individuals (BMI < 18.5) have the highest mortality risk. This is because being underweight can indicate malnutrition, weakened immune system, and increased vulnerability to diseases and infections. Additionally, underweight individuals may have reduced muscle mass and bone density, which can lead to various health complications and a higher risk of mortality.

  Moderately/Extremely Obese (BMI >= 35)
Correct Answer
E. Moderately/Extremely Obese (BMI >= 35)

Explanation
The given correct answer is Moderately/Extremely Obese (BMI >= 35). This category has the second highest mortality risk because individuals with a BMI of 35 or higher are considered to be severely obese, which significantly increases the risk of various health conditions such as heart disease, diabetes, and certain types of cancer. These health conditions can lead to a higher mortality rate compared to other BMI categories.

- E.
  
  Moderately/Extremely Obese (BMI >= 35)
Correct Answer
B. Normal Weight (BMI 18.5-24.9)

Explanation
The question asks for the BMI category with the third highest mortality risk. The BMI categories are listed in order from lowest to highest BMI range. Since the question specifies "third highest," we can determine that the category with the highest mortality risk is "Moderately/Extremely Obese (BMI >= 35)" and the second highest is "Mildly Obese (BMI 30-34.9)." Therefore, the category with the third highest mortality risk would be "Normal Weight (BMI 18.5-24.9)."

Correct Answer
D. Mildly Obese (BMI 30-34.9)

Explanation
The question asks for the BMI category with the fourth highest mortality risk. The BMI categories are listed in ascending order, from underweight to moderately/extremely obese. Since mildly obese (BMI 30-34.9) is the fourth category listed, it is the answer.

Which BMI category has the lowest mortality risk?
- A.
  
  Underweight (BMI < 18.5)
- B.

- E.
  
  Moderately/Extremely Obese (BMI >= 35)
Correct Answer
C. Overweight (BMI 25-29.9)

Explanation
The correct answer is "Overweight (BMI 25-29.9)". This category has the lowest mortality risk compared to the other BMI categories listed. The underweight category (BMI < 18.5) often carries a higher mortality risk due to potential malnutrition and weakened immune system. The mildly obese, moderately obese, and extremely obese categories (BMI 30-34.9 and BMI >= 35) have higher mortality risks associated with conditions such as heart disease, diabetes, and certain cancers. The normal weight category (BMI 18.5-24.9) also has a relatively low mortality risk, but the overweight category has been shown to have slightly better health outcomes overall.
