The correct answer is Lahaul and Spiti.
Lahaul and Spiti is a district in the Indian state of Himachal Pradesh. It is the least populous district in the state, with a population of 31,000 as of 2011. The district is also the least developed in the state, with a literacy rate of 62.1% as of 2011.
The low literacy rate in Lahaul and Spiti is due to a number of factors, including the remoteness of the district, the harsh climate, and the lack of educational facilities. The district is located in the Himalayas, and is surrounded by mountains on all sides. The climate is cold and dry, and the roads are often impassable during the winter. This makes it difficult for people to access education and other services.
The lack of educational facilities is another major factor contributing to the low literacy rate in Lahaul and Spiti. There are only a few schools in the district, and they are often located far from people’s homes. This makes it difficult for children to attend school, especially if they have to walk long distances.
The government has taken some steps to improve the literacy rate in Lahaul and Spiti. They have opened new schools in the district, and they have also started providing scholarships to students. However, more needs to be done to improve the situation. The government needs to invest more in education in the district, and they need to make it easier for people to access education.
The other options are incorrect because they have higher literacy rates than Lahaul and Spiti. Kullu has a literacy rate of 84.1%, Chamba has a literacy rate of 81.5%, and Solan has a literacy rate of 83.3%.
