Correct Answer : Option (C) - 2, 3 and 4 only
Note :
The first statement is wrong as it is under the UN convention against trans-national organized crime.
The United Nations Convention against Corruption is the only legally binding universal anti-corruption instrument.
The Convention UNTOC is supplemented by three Protocols, which target specific areas and manifestations of organized crime: the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children; the Protocol against the Smuggling of Migrants by Land, Sea and Air; and the Protocol against the Illicit Manufacturing of and Trafficking in Firearms, their Parts and Components and Ammunition.
Countries must become parties to the Convention itself before they can become parties to any of the Protocols. Statements 2, 3 and 4 are correct.
