• B. BMI greater than or equal to 30
• C. BMI between 25 and 29.9
• D. BMI between 18.5 and 24.9

Answer: (B)

The definition of obesity according to Body Mass Index (BMI) is a BMI greater than or equal to 30. This classification is part of a standardized system used to categorize individuals based on their body weight relative to their height. A BMI in this range indicates that an individual may have excess body fat, which can lead to various health risks, including heart disease, diabetes, and certain cancers.

Understanding BMI categories helps in identifying obesity and managing health risks associated with it. This classification is widely accepted in medical and health guidelines, providing a clear threshold for identifying those who may benefit from interventions aimed at weight management and overall health improvement.
