Which of the following statements with regard to the definition of "industry" is/are correct? (a) A…

Under the triple test laid down in "Bangalore Water Supply and Sewerage Board v. A. Rajappa" (1978) and reflected in Section 2(p) of the Industrial Relations Code, 2020 (formerly Section 2(j) of the Industrial Disputes Act, 1947), any systematic activity carried on by co-operation between an employer and workers for the production, supply, or distribution of goods or services to satisfy human wants is an "industry". Both a book shop (a) and a cooperative milk society (b) qualify as industries, whereas statements (c) and (d) are incorrect because a dock labour board and a hair-cutting establishment employing workers are also industries. Thus, only (a) and (b) are correct.
