If irrigation expansion increases crop profit but reduces groundwater what does geography explain?

Correct answer: Integration of development benefit and resource depletion

The direct answer is C: integrating development benefits with resource depletion. Geography studies both human benefits and environmental costs. First, irrigation supplies more water to fields. Second, crop production and farmer profit may increase. Third, repeated or excessive pumping can lower the groundwater table. Fourth, future farmers, households and ecosystems may face water scarcity. Therefore, the complete geographical explanation must consider economic development, resource use and sustainability together. Option C is correct because it includes both the gain from irrigation and the loss or pressure on groundwater. Option A is incomplete because it notices profit but ignores depletion and future effects. Option B is wrong because merely naming water or a water body explains nothing about the relationship between irrigation, profit and declining groundwater. Option D is irrelevant because a list of farmers does not analyse development or environmental change. The exam cue is to look for both sides whenever an activity brings a benefit but creates a cost: production versus depletion, present gain versus future sustainability. Good geographical analysis does not reject all development; it asks whether development can continue without exhausting resources.
