B. safe drinking water और agriculture दोनों salinity से प्रभावित हो सकते हैंBoth safe drinking water and agriculture may be affected by salinity
Simple Explanation
Strong flood protection one hazard को reduce करती है, लेकिन rising salinity groundwater quality और agricultural productivity दोनों को नुकसान पहुंचा सकती है। यदि drinking water expensive हो जाए और farming income घटे तो households safer or better-served areas की ओर migrate कर सकते हैं। इसलिए दूसरा विकल्प सही है। पहला विकल्प hazard reduction को complete environmental security मानता है, जो गलत है। Expert-level analysis में multiple environmental stresses को अलग-अलग पहचानना आवश्यक है। / Strong flood protection reduces one hazard, but rising salinity can damage both groundwater quality and agricultural productivity. If drinking water becomes costly and farm incomes decline, households may migrate toward safer or better-served areas. Therefore, the second option is correct. The first option wrongly treats reduction of one hazard as complete environmental security. Expert-level analysis requires distinguishing multiple environmental stresses rather than assuming that protection against one removes all others.
