Body Mass Index (BMI) is obtained by:

Correct option is D

The correct answer is (D) weight in kg / square of height in metre

Explanation:
• Body Mass Index (BMI) is a simple, widely used metric to estimate a person's body fat based on their height and weight. The mathematical formula is defined as a person's weight in kilograms divided by the square of their height in meters ($$BMI = \frac{\text{weight (kg)}}{\text{height (m)}^2}$$).
• International health organizations use BMI ranges to screen for different weight categories, helping to assess potential health risks associated with underweight, overweight, or obesity.
• While BMI is a helpful screening tool, it does not directly measure body fat percentage and may not fully reflect health status in individuals with high muscle mass, such as athletes.

Information Booster:
• The World Health Organization (WHO) classifies BMI values as follows: Underweight (below 18.5), Normal weight (18.5 to 24.9), Overweight (25 to 29.9), and Obese (30 and above).

Additional Knowledge:
• Options A, B, and C: These options list incorrect arrangements of the variables or use wrong units (like centimeters instead of meters), which will not yield the standard BMI value.
