In which situation is a positive relationship between GDP and welfare most likely?

Correct answer: When real output, employment, public health, and environmental quality improve together

GDP is more likely to reflect higher welfare when increased real production is accompanied by productive employment, better health, and a healthier environment. These conditions suggest that gains are reaching people and are not being achieved by shifting large costs onto society or future generations. Pollution, inequality, defensive spending, and resource depletion can raise measured output while weakening welfare, so A is the best answer.
