Which principle among the following was added to the Directive Principles of State Policy by the 42nd Amendment to the Constitution ?
Explanation
Option (b) is correct because Article 43A, which mandates the State to take steps to secure the participation of workers in the management of industries, was inserted by the 42nd Constitutional Amendment Act, 1976. Option (a) is a common distractor but is incorrect because "equal pay for equal work" (Article 39d) was part of the original Directive Principles and not added by amendment. The core concept tested is the evolution of Directive Principles of State Policy (DPSP) and the specific additions made by the "Mini-Constitution" (42nd Amendment).
