The correct answer is option 2, 2005.

The "Rajiv Gandhi Grameen Vidyutikaran Yojana" was launched in 2005. This scheme was introduced as a part of the National Common Minimum Programme to provide electricity to all the rural households in India. The objective of the scheme was to ensure electrification of all villages and rural households by setting up new power infrastructure in rural areas.

Option 1, 2004, is incorrect because the scheme was launched in 2005 and not in 2004.
