The correct answer is option (A), Dantewada.
The population growth rate of Dantewada district in the period of 2001-2011 was 12.4%, which is the lowest among the five districts mentioned in the question. The population growth rate of Narayanpur district was 13.4%, Bastar district was 14.2%, Kanker district was 15.2%, and Korea district was 16.1%.
The low population growth rate of Dantewada district can be attributed to a number of factors, including the poor infrastructure in the district, the lack of employment opportunities, and the high incidence of violence. The poor infrastructure in the district makes it difficult for people to access basic services such as education, healthcare, and transportation. The lack of employment opportunities forces many people to migrate to other districts in search of work. The high incidence of violence in the district has led to the displacement of many people.
The low population growth rate of Dantewada district is a cause for concern. The district is already facing a number of challenges, including poverty, malnutrition, and lack of access to basic services. The low population growth rate will only make it more difficult for the district to address these challenges.
