Explanation:
RTI is a fundamental right of every citizen of India which ensures transparency and accountability in the functioning of the government. It enables citizens to seek information from any public authority or government department regarding their functioning, decisions, policies, and activities.

The RTI Act was passed by the Indian Parliament in 2005 and came into force on 12th October 2005. It empowers citizens to access information held by public authorities and makes the government more accountable to the people.

Under the RTI Act, any citizen of India can request information from a public authority by submitting an application in writing or through electronic means. The public authority is required to provide the information within 30 days of receiving the application. If the information is not provided within the stipulated time, the citizen can file an appeal with the higher authorities.

The RTI Act has played a significant role in promoting transparency, accountability, and good governance in India. It has helped in exposing corruption, irregularities, and malpractices in various government departments and has empowered citizens to participate in the democratic process.
