In which condition will population change affect food security the most?

Correct answer: When population grows rapidly through births and in-migration but food supply grows slowly

The correct answer is A. Food security means that people can regularly obtain enough safe and nutritious food. First, births and in-migration add people to the population. Second, a rapidly growing population increases the total demand for food. Third, if food production or supply grows slowly, it may not keep pace with that demand. The result can be greater pressure on availability and access to food. B is less threatening because fewer people and more food generally improve food availability per person. C creates no food demand, so it cannot create the stated pressure. D removes scarcity in the situation described. The important comparison is not population size alone but the relationship between the number of people and the growth of food supply. Memory cue: rapid demand growth plus slow supply growth creates food-security pressure.
