Which option gives a correct economic result of population growth?

Correct answer: Job seekers and demand for employment may increase

Correct answer: A. Population growth means that the number of people living in an area increases. More people may need work, so the number of job seekers and the demand for employment can rise. If the economy does not create enough jobs, unemployment or underemployment may increase; if jobs and skills grow together, the larger population can also become a productive workforce. Option A is correct because it states a possible economic result, not an unavoidable result. B is wrong because population growth does not necessarily dry rivers; river flow depends on rainfall, climate, extraction and other factors. C is wrong because the physical area of a region does not automatically increase when its population grows. D is wrong because income depends on wages, productivity, prices and employment, so it cannot immediately double for every family. Memory cue: more people usually mean greater demand for both work and resources.
