All India Bar Examination (AIBE) 5-V Previous Year Question Papers with Answers

The correct option is C: Registrar of trade unions 

This is because the Trade Unions Act, 1926, provides for the registration of trade unions and defines the role and functions of the Registrar of trade unions. According to Section 3 of the Act, the appropriate Government (either the Central Government or the State Government) can appoint a Registrar of trade unions for each State, and also any Additional or Deputy Registrar of trade unions as it deems necessary. The Registrar of trade unions is responsible for maintaining a register of trade unions, issuing certificates of registration, cancelling or modifying the registration of trade unions, calling for further particulars or requiring alteration of name of any trade union, inspecting the books and accounts of registered trade unions, and receiving annual returns from them. The Registrar of trade unions also has the power to make inquiries and investigations into the affairs of any trade union, and to hear and decide any appeal against his orders or decisions. Therefore, the Registrar of trade unions is the principal regulator envisaged under the Trade Unions Act, 1926.

Option A is incorrect because there is no such authority as Regulator of trade unions under the Trade Unions Act, 1926. The Act only mentions the Registrar of trade unions as the official in charge of regulating the registration and functioning of trade unions.

Option B is incorrect because there is no such authority as Inspector of trade unions under the Trade Unions Act, 1926. The Act only empowers the Registrar of trade unions to inspect the books and accounts of registered trade unions, and to make inquiries and investigations into their affairs.

Option D is incorrect because there is no such authority as Industrial relations committee under the Trade Unions Act, 1926. The Act does not deal with the industrial relations or disputes between employers and employees, or between different trade unions. The Industrial Disputes Act, 1947, is a separate legislation that deals with these matters.
