Step 1: Understanding the Concept:
The Industrial Relations Code, 2020, was enacted to consolidate and simplify three major existing labour laws.
Step 2: Detailed Explanation:
- The Code consolidates: (1) The Industrial Disputes Act, 1947; (2) The Trade Unions Act, 1926; and (3) The Industrial Employment (Standing Orders) Act, 1946.
- The Industries (Development and Regulation) Act, 1951, focuses on industrial licensing and regulation of production capacity, not industrial relations between employers and employees; thus, it is not part of this Code.
Step 3: Final Answer:
The IDR Act is not included in the Code. Option (A) is correct.
