Which of the following is a problem associated with mega c cities

There are several problems associated with mega-cities, but here is one common issue:

1. Overpopulation and overcrowding: Mega-cities often have extremely high population densities, leading to overcrowded living conditions. This can result in strains on infrastructure, such as transportation systems, housing, healthcare, and sanitation facilities. Overpopulation also contributes to increased pollution levels, crime rates, and social inequalities.
