The correct answer is (a) 2006-11.
The Eleventh Five Year Plan (2006-2011) was the eleventh five-year plan of India. It was launched by the United Progressive Alliance (UPA) government in 2006. The plan focused on inclusive growth, infrastructure development, and agriculture. It also aimed to reduce poverty and improve the quality of life of the people.
The plan was implemented in two phases: the first phase from 2006 to 2009 and the second phase from 2009 to 2011. The plan was successful in achieving some of its goals, such as reducing poverty and improving the quality of life of the people. However, it was not able to achieve all of its goals, such as infrastructure development and agriculture.
The Eleventh Five Year Plan was a significant step in the development of India. It helped to improve the lives of millions of people and laid the foundation for future growth.
The other options are incorrect because they do not correspond to the actual period of the Eleventh Five Year Plan.
