According to Freedom of States of India Report 2013, the State which tops the rank is

Maharashtra
Andhra Pradesh
Gujarat
Haryana

The correct answer is (a) Maharashtra.

The Freedom in the World 2013 report, published by Freedom House, is an annual survey of the state of freedom in 195 countries and 15 territories. The report assesses the degree of political rights and civil liberties enjoyed by individuals in each country and territory, and assigns each country a numerical rating and a status of “Free,” “Partly Free,” or “Not Free.”

In the 2013 report, Maharashtra was ranked as “Free,” with a score of 2.0. This score indicates that Maharashtra has a “free” political system, with a functioning multiparty democracy and a significant degree of respect for civil liberties.

The other options are incorrect because they are not ranked as “Free” in the 2013 report. Andhra Pradesh is ranked as “Partly Free,” with a score of 3.5. Gujarat is ranked as “Partly Free,” with a score of 3.5. Haryana is ranked as “Partly Free,” with a score of 3.5.

The Freedom in the World report is based on a variety of sources, including expert assessments, media reports, and government documents. The report is widely respected as a reliable and objective assessment of the state of freedom around the world.
