The correct answer is: A. 2 lakh or more.
The Ward Committee shall be constituted for the population of 2 lakh or more. This is as per the provisions of the 74th Amendment Act of the Constitution of India, which provides for the establishment of Ward Committees in urban areas. The Act states that a Ward Committee shall be constituted for a population of not less than 2 lakh.
The Ward Committee is a local body that is responsible for the day-to-day administration of a ward. It is headed by a Ward Councillor, who is elected by the residents of the ward. The Ward Committee has the power to make decisions on matters such as sanitation, water supply, street lighting, and public health.
The Ward Committee is an important part of the urban local government system. It provides a forum for the residents of a ward to participate in the decision-making process and to hold the local government accountable.
The other options are incorrect because they do not meet the minimum population requirement for the constitution of a Ward Committee.
