Correct answer: A. Population aged 0-14 and 65+ years to population aged 15-64 years

The dependency ratio measures the dependent population (those under 15 and over 64) relative to the working-age population (15-64 years). It includes both young and old dependents. Option C is the child dependency ratio only. Option B is the old-age dependency ratio only. Option D is not a standard demographic measure.
