Explanations:Economic challenges in urban areas such as Mumbai are multifaceted and can include issues related to employment, income, and economic opportunities. The economic well-being of a city's population is significantly influenced by the types of jobs available and the pay associated with those jobs. Low-skilled jobs that are poorly paid can lead to widespread poverty and economic inequality, which are critical economic challenges.
Option A describes air pollution, which is a significant environmental issue. While air pollution can have economic consequences, such as increased healthcare costs and reduced productivity, it is primarily an environmental challenge rather than a direct economic one. The focus here is on the quality of the environment and its impact on health and quality of life.
Option B addresses the water supply issue in slums, which is a social and infrastructure challenge. Inadequate water supply can affect the daily lives of residents and can have indirect economic impacts, such as reduced productivity and health issues. However, it is not a direct economic challenge like employment conditions.
Option C correctly identifies an economic challenge. The availability of low-skilled and poorly paid jobs directly impacts the economic well-being of the population. This situation can lead to widespread poverty, reduced consumer spending, and limited economic growth. It is a fundamental economic issue that affects the overall economic health of the city.
Option D describes water pollution, which is another environmental issue. While water pollution can have economic consequences, such as the cost of cleaning up polluted water and the impact on industries that rely on clean water, it is not a direct economic challenge like employment conditions.
In summary, economic challenges in urban areas like Mumbai are best understood by focusing on issues that directly impact the economic well-being of the population, such as the availability of well-paying jobs. Low-skilled and poorly paid jobs are a significant economic challenge that can lead to poverty and economic inequality, making Option C the correct answer.
