The correct answer is A. Wage Court.
A Wage Court is a judicial body that is established to settle industrial disputes. It is composed of a judge and two assessors, one representing employers and one representing employees. The Wage Court has the power to make awards that are binding on both parties to the dispute.
A Works Committee is a body that is established by an employer to represent the interests of employees in the workplace. It is composed of representatives of both the employer and the employees. The Works Committee has the power to discuss and resolve issues that affect the workplace, such as working conditions, pay, and benefits.
A Conciliation Officer is a person who is appointed by the government to help resolve industrial disputes. They are not a judge and they do not have the power to make awards. However, they can help the parties to reach a settlement by providing information, advice, and mediation.
A Board of Conciliation is a body that is established by the government to investigate and conciliate industrial disputes. It is composed of representatives of the government, employers, and employees. The Board of Conciliation has the power to make recommendations to the parties to the dispute, but these recommendations are not binding.
In conclusion, the Wage Court is not a part of the machinery that settles industrial disputes. The other options, Works Committee, Conciliation Officer, and Board of Conciliation, are all part of the machinery that settles industrial disputes.
