In which condition will temporary migration also be important in planning?

Correct answer: When many people come for seasonal work for a few months

Direct answer: A. Temporary migration means that people move for a limited period and later return or move elsewhere. Even though these migrants do not stay permanently, planners must count them while they are present. A large seasonal workforce may need temporary housing, drinking water, sanitation, transport, health care, safety arrangements, and sometimes schools or food services. If planning considers only the permanent population, these temporary needs may be missed. A is correct because many people arriving for several months can sharply increase local demand during that period. B is wrong because no arrival creates no temporary migrant demand. C may affect population change, but it does not by itself describe temporary migration. D does not explain why planning would need to consider temporary migrants. The important distinction is duration: short-term movement can still have real short-term effects. Memory cue: temporary people still require permanent-quality planning while they are present.
