Concept:Democracy faces difficulties when it must expand to include many different regions, cultures, and ethnic groups.
Explanation:A democratic system requires fulfilling the interests of all people.
However, in large and diverse countries like India, there are many cultural, ethnic, and religious groups.
It becomes very hard to satisfy the demands of every group at the same time.
This is a major challenge because democracy must respect diversity while also making decisions for the whole nation.
Other challenges include frequent changes in leaders, political competition without morality, and delays due to consulting many people.
Among the given options, “expansion of democracy across regions, culture, etc.” directly describes this difficulty of managing diversity.
The other options — distribution of power, distribution of abundant resources, and equality in wages — are not considered primary challenges to democracy.
Answer:D. expansion of democracy across regions, culture, etc.
