Which answer correctly includes both negative and positive effects of rivers?

Answer and explanation

Correct answer: Floods and bank erosion along with irrigation and fertile alluvial soil

Rivers supply water for irrigation and deposit alluvial soil on floodplains, making land fertile. However, heavy rainfall or excessive river discharge can cause floods, and fast-flowing water can erode riverbanks. Therefore, option A correctly states both beneficial and harmful effects. Option C is the closest distractor: irrigation and fertile soil are benefits, but rivers can still pose risks of flooding and erosion. Exam tip: When asked about river impacts, identify at least one benefit and one hazard.
