The correct answer is (c) Kerala, Tamil Nadu, Delhi, Haryana.
The Educational Development Index (EDI) is a composite index that measures the progress of states and union territories in India in the field of education. It was developed by the Ministry of Human Resource Development (MHRD) and released in February 2011. The EDI is based on four indicators: literacy rate, gross enrolment ratio (GER) at the primary, secondary and higher education levels, and gender parity index (GPI) in education.
Kerala has been ranked first in the EDI for the past several years. It has a literacy rate of 94%, which is the highest in the country. The GER at the primary level is 100%, and the GER at the secondary level is 80%. The GPI in education is 1.00, which means that there is no gender gap in education in Kerala.
Tamil Nadu is ranked second in the EDI. It has a literacy rate of 80%, which is the second highest in the country. The GER at the primary level is 100%, and the GER at the secondary level is 80%. The GPI in education is 0.99, which means that there is a very small gender gap in education in Tamil Nadu.
Delhi is ranked third in the EDI. It has a literacy rate of 86%, which is the third highest in the country. The GER at the primary level is 100%, and the GER at the secondary level is 80%. The GPI in education is 0.98, which means that there is a small gender gap in education in Delhi.
Haryana is ranked fourth in the EDI. It has a literacy rate of 76%, which is the fourth highest in the country. The GER at the primary level is 100%, and the GER at the secondary level is 80%. The GPI in education is 0.97, which means that there is a moderate gender gap in education in Haryana.
The other options are incorrect because they do not include Kerala, which has been ranked first in the EDI for the past several years.
