Which statement is not correct about international organizations $($IOs$)?$

IOs are conceptually different from NGOs.

They are trying to lessen the gap between citizens and themselves through special newsletters, conferences, and so on

The mid$-1980$s rise of NGO interaction with IOs has led many IOs to create mechanisms for discussion between themselves and the NGOs.

United Nations and World Bank are the examples of IOs.

They would not be considered illegitimate in any ways even if they did not involve civil society of NGO actors.
