Under the Right to Information (RTI) Act, 2005, and subsequent rules and practices: Statement 1 is correct. Applicants can submit applications directly by hand to the PIO or the designated receiving point of the Public Authority. Statement 2 is correct. Many public authorities have provisions for receiving RTI applications via email, subject to fulfilling certain requirements like fee payment. Statement 3 is correct. Section 6(3) of the RTI Act mandates that if an application is made to a Public Authority which does not hold the requested information, the PIO of that authority shall transfer the application to the appropriate Public Authority within five days. Thus, a PIO receives applications transferred from other public authorities. Statement 4 is correct. Assistant Public Information Officers (APIOs) are designated at sub-divisional or sub-district levels to receive RTI applications and forward them to the respective PIOs or nodal officers. Therefore, PIOs receive applications forwarded by APIOs.
