The Saansad Adarsh Gram Yojana is a government initiative launched in 2014, aiming to turn selected villages into model villages. Members of Parliament are required to adopt villages and take responsibility for their development. The statement mentioned in option 1 is incorrect because the Saansad Adarsh Gram Yojana was not launched on the birth anniversary of Lai Bahadur Shastri.

Option 2 is a correct statement, as the objective of the Yojana is for MPs to adopt villages and work towards developing them into model villages. Option 3 is also correct, as District Magistrates are appointed as the coordinators of the Saansad Adarsh Gram Yojana. They play a crucial role in implementing and monitoring the development work in the adopted villages.

Option 4 is also a correct statement. According to the guidelines of the Yojana, a Rajya Sabha MP has to choose a Gram Panchayat in the state from which they were elected to adopt and develop. The Saansad Adarsh Gram Yojana focuses on creating model villages in rural areas and improving the overall quality of life for the villagers.
