Explanation:

Option 4th is correct.

• The Central Information Commission was established by the Central Government in 2005, under the provisions of the Right to Information Act (2005). It is not a constitutional body. 
• The Commission consists of a Chief Information Commissioner and not more than ten Information Commissioners.
• They are appointed by the President on the recommendation of a committee consisting of the Prime Minister as Chairperson, the Leader of Opposition in the Lok Sabha and a Union Cabinet Minister nominated by the Prime Minister.
• The Chief Information Commissioner and an Information Commissioner shall hold office for such terms as prescribed by the Central Government or until they attain the age of 65 years, whichever is earlier.
• They are not eligible for reappointment.
• The Right to Information (Amendment) Act, 2019 provided that the Chief Information Commissioner and an Information Commissioner shall hold office for such terms as prescribed by the Central Government.
• Before this amendment, their term was fixed for 5 years.

Hence all statements are incorrect.
