In which condition will population growth affect food security more?

Correct answer: When food production is less than demand

Correct answer: A, when food production is less than demand. Food security means that people can obtain enough safe and nutritious food. First compare the amount of food available with the amount needed by the population. If population increases while food production does not keep pace, demand becomes greater than supply. This can create pressure on food availability, access, and affordability. Option A is correct because a shortage relative to demand makes the effect of population growth on food security stronger. Option B is wrong because production greater than demand generally reduces shortage pressure, although distribution still matters. Option C is wrong because a decreasing population usually reduces total food demand, all else being equal. Option D is not the best answer: strong distribution can improve access, but it does not remove the problem if total production is below demand. Memory cue: food security depends on both supply and access; first check whether food supply can meet demand.
