The Right to Information Act of Parliament received the assent of the President of India on

The correct answer is C) 15 June 2005. The RTI Act received the President's assent on this date, after Parliament passed it in May and June 2005. The Act was published in the Gazette on 21 June 2005.

Why the others are wrong:

• A) 15 May 2005 is too early. Parliament had not yet completed passage of the Bill on this date.
• B) 5 June 2005 does not match the assent date.
• D) 12 October 2005 is the date the Act came into force (commencement), not the date of assent. This is the trap.

The core concept is the difference between passage, assent, publication and commencement. A law becomes valid on assent but may come into force on a later notified date. For Mains, the RTI Act links to Article 19(1)(a) and to governance debates on transparency, accountability and the limits set by Section 8 exemptions.

Trap: Treating the date the Act became operational as the date of assent.
