In Madhya Pradesh, Mukhyamantri Kanya Vivah Yojana was launched in the year…

State-run welfare schemes named after the Chief Minister (a "Mukhyamantri ___ Yojana") are each tied to a specific notification/launch date recorded in the state government's own official scheme documentation; a fill-in-the-year item on such a scheme is answered by matching the offered years against that official record, not by the scheme's broader popular era.

The Government of Madhya Pradesh officially launched the Mukhyamantri Kanya Vivah Yojana — a scheme providing financial assistance toward the marriage expenses of daughters from economically weaker families — on 1 April 2006, during Chief Minister Shivraj Singh Chouhan's tenure. This date is confirmed by Madhya Pradesh's official CM Helpline scheme record and independently corroborated by district-government portals (e.g., Sidhi district), both of which fix the scheme's commencement in 2006. Hence 2006 is the correct year.

• 2005: this year comes before the scheme's documented April 2006 launch.

• 2007: this year comes after the scheme's documented 2006 launch, and instead corresponds to a separate Madhya Pradesh welfare initiative, the Ladli Laxmi Yojana, launched in 2007.

• None of the above: ruled out because the state's own official scheme record does fix a specific year — 2006 — within the years offered.
