Which one of the following is not an 'Industry'?

Under the Industrial Disputes Act, 1947, 'industry' is defined very broadly to include any systematic activity carried on by cooperation between employers and employees for the production of goods or services. The Forest Department (a government department) and Khadi and Village Industries Board fall under this definition. However, the Indian Red Cross Society is a charitable humanitarian organization, not an 'industry' under labor law. The answer key correctly identifies it as not being an industry, though there's a minor typo in option B ('Federation at' should likely be 'Federation of').
