This question tests whether the four composite claims about the Assertion (A) and Reason (R) correctly capture the settled position on what counts as an "industry" under Section 2(j) of the Industrial Disputes Act, 1947. Begin from the governing rule itself - the Triple Test laid down in Bangalore Water Supply and Sewerage Board v. A. Rajappa - and apply it directly to each option.
Working forward from the statutory test to the facts eliminates three of the four composite claims and confirms that (R) is both true and the true explanation for how the situation in (A) resolves under Section 2(j).
Therefore, the correct answer is Both (A) and (R) are true, and (R) is the correct explanation of (A).
