## **Core Concept**
The Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight, and obesity in adults. It is calculated by dividing the person's weight in kilograms by the square of their height in meters (**kg/m^2**). The BMI is a widely used tool for assessing weight status.

## **Why the Correct Answer is Right**
To calculate the BMI of a male whose weight is 89 kg and height is 182 cm, first convert the height into meters. Since 1 meter = 100 cm, 182 cm = 1.82 meters. Then, calculate the BMI using the formula: BMI = weight (in kg) / height (in meters)^2. Substituting the given values: BMI = 89 / (1.82)^2 = 89 / 3.3124 ≈ 26.9. The correct answer should closely match this calculation.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Without a specific value, it's not possible to directly refute, but any option not equal to 26.9 would be incorrect based on our calculation.
- **Option B:** Similarly, without a value, direct refutation isn't possible, but it would be incorrect if not approximately 26.9.
- **Option C:** This option would be incorrect if its value does not match 26.9, based on the calculation.
- **Option D:** This is the correct answer, so the others are incorrect by comparison.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that BMI categories are classified as follows: underweight (<18.5), normal weight (18.5-24.9), overweight (25-29.9), and obese (≥30). Therefore, a BMI of approximately 26.9 falls into the overweight category. ## **Correct Answer:** **C. 26.9**
