Based on the provisional figures of Census 2011 the correct ascending order of the four States of India having the lowest literacy rate is

• Poverty: Many people in these states live in poverty, which can make it difficult to access education.
• Lack of infrastructure: Some of these states have poor infrastructure, which can make it difficult to build schools and provide education services.
• Social factors: In some of these states, there are social factors that discourage people from getting an education, such as gender discrimination or caste discrimination.
• Language barriers: In some of these states, there are language barriers that can make it difficult for people to learn to read and write.

The government has taken some steps to address the issue of low literacy rates in these states, such as building more schools and providing scholarships to students. However, more needs to be done to ensure that everyone in these states has access to quality education.
