Final answer:
People in Afghanistan struggle to access water due to the country being landlocked and undeveloped, which impedes the establishment of necessary infrastructure for water supply.
Step-by-step explanation:
The country where people have difficulty accessing water due to being landlocked and undeveloped is Afghanistan. This is because Afghanistan's geopolitical history and lack of development hinder easy access to water resources.
Afghanistan is a landlocked region that has historically suffered under various conflicts, limiting its development and access to clean water. In contrast, countries like France, Australia, and China, although they have their water management challenges, are not landlocked and have more developed infrastructures to handle water supply issues.
Many countries, especially undeveloped or developing nations, face severe water access issues due to economic constraints that prevent them from implementing large-scale water projects like those seen in richer nations.
