The correct answer is (a) 2015-16.
Samagra Shiksha Abhiyan (SSA) is a flagship programme of the Government of India for the universalization of elementary education (UEE) in the country. It was launched in 2015-16 as an umbrella programme integrating the erstwhile Sarva Shiksha Abhiyan (SSA), Rashtriya Madhyamik Shiksha Abhiyan (RMSA), and the Teacher Education Programme (TEP).
The SSA aims to provide quality elementary education to all children in the age group of 6-14 years by 2020. It focuses on improving access, equity, quality, and efficiency in elementary education. The SSA is implemented through the state governments and union territories.
The SSA has been successful in achieving many of its goals. The gross enrolment ratio (GER) in elementary education has increased from 93.2% in 2015-16 to 97.3% in 2019-20. The dropout rate has also declined from 10.1% in 2015-16 to 6.3% in 2019-20. The SSA has also made significant progress in improving the quality of education. The learning outcomes of students have improved, and the infrastructure in schools has been upgraded.
The SSA is a major step towards achieving the goal of universal education in India. It has made significant progress in improving access, equity, quality, and efficiency in elementary education. The SSA is expected to continue to play a key role in the development of elementary education in India in the years to come.
The other options are incorrect because they are not the years in which the SSA was started.
