Correct Answer: D
Body Mass Index (BMI) is a screening tool that uses height and weight to estimate whether a person's weight category may pose health risks. Standard BMI categories commonly used in health education classify underweightas a BMIbelow 18.5,healthy weightas18.5-24.9,overweightas25.0-29.9, and obesity at higher values. Based on these categories, the range that aligns with underweight among the given choices is14.5-
18.5 (D)because it falls at and below the 18.5 cutoff (with most of the range being below 18.5).
OptionB (18.5-24.9)is the typical healthy-weight range. OptionC (25.0-29.9)matches the overweight category. OptionA (10.0-14.5)is extremely low and may indicate severe underweight, but the question asks for the BMI range "associated with being underweight" in general; the broader underweight-related range offered isD.
From a wellness perspective, being underweight can be linked with concerns such as reduced energy, nutrient deficiencies (iron, calcium, vitamin D, B vitamins), lowered immune resilience, or decreased bone density- especially if underweight results from inadequate intake or underlying medical issues. That said, BMI is a screening measure, not a diagnosis: it does not directly measure body fat, muscle mass, or overall health. A person with a low BMI who is experiencing fatigue, frequent illness, or unintended weight loss should be assessed by a healthcare professional to identify causes and appropriate nutrition strategies.
