Union Government Responsibilities Analysis

The question asks us to identify which of the given responsibilities fall under the purview of the Union Government of India. The Indian Constitution divides legislative powers between the Union (Central) Government and the State Governments through different Lists (Union List, State List, Concurrent List).

Understanding Government Responsibilities

The Union Government is primarily responsible for subjects of national importance, such as defense, foreign affairs, currency, banking, communication, and census. State Governments handle matters related to public order, police, health, agriculture, and local governance within their respective states.

Analyzing Each Responsibility

Responsibility A: Making peaceful relations with China

Establishing and maintaining foreign relations with other countries, including ensuring peaceful relations, is exclusively the domain of the Union Government. This falls under 'Foreign Affairs', which is listed in the Union List of the Constitution.

Responsibility B: Maintenance of jail

The maintenance of law and order, including prisons and jails within a state, is generally a responsibility of the State Government. This subject is typically placed under the State List in the Seventh Schedule of the Indian Constitution.

Responsibility C: Introduction of new trains in a State

Railways are a crucial part of national infrastructure and are administered by the Union Government. The planning, development, and introduction of new trains or railway lines across the country, even if they operate within a specific state, fall under the Union Government's responsibility as part of the 'Railways' subject in the Union List.

Responsibility D: Census

The collection and compilation of data related to the population, known as the Census, is a significant national undertaking. This is explicitly mentioned in the Union List of the Constitution, making it a responsibility of the Union Government.

Consolidating Union Government Responsibilities

Based on the analysis, the responsibilities that come under the Union Government are:

• A. Making peaceful relations with China (Foreign Affairs)
• C. Introduction of new trains in a State (Railways)
• D. Census

The maintenance of jail (B) is a State Government responsibility.

Conclusion

Therefore, the correct option includes responsibilities A, C, and D as functions of the Union Government.
