Step 1: Industrial Disputes Act, 1947 Overview:
The Industrial Disputes Act, 1947, is India's main law for handling industrial disputes. It provides a legal structure and sets up bodies for resolving these issues.
Step 2: Option Analysis:
(A) Labour Court: This court, established by the Act, settles disputes on topics in the Second Schedule (e.g., firing employees, strike legality). Therefore, it's part of the legal framework.
(B) Collective Bargaining: This is a {process} or a {method} where employers and employees negotiate to set working conditions. While key to resolving disputes, it's not a formal 'machinery' {created by the Act} like courts or officers.
(C) Conciliation Officer: This officer, appointed under the Act, mediates and helps settle industrial disputes. Therefore, it's part of the legal framework.
(D) Board of Conciliation: This body, formed under the Act, includes a chairman and members, and helps settle disputes. Therefore, it's part of the legal framework.
Step 3: Correct Machinery Identification:
The Act's formal framework includes Conciliation Officers, Boards of Conciliation, Courts of Inquiry, Labour Courts, Industrial Tribunals, and National Tribunals. Hence, (A), (C), and (D) are correct. Collective Bargaining is a process, not a statutory body.
Step 4: Final Answer:
The correct combination of machinery for settling industrial disputes under the Act is (A), (C), and (D), which corresponds to option (C).
