The correct answer is: d) Aizawl.
Aizawl is the capital of Mizoram and has the highest literacy rate in the state. The literacy rate in Aizawl is 94.3%, which is significantly higher than the national average of 74.04%. The high literacy rate in Aizawl is due to a number of factors, including the state’s strong focus on education, the availability of quality educational institutions, and the relatively high socioeconomic status of the population.
Serchhip is the second most literate district in Mizoram, with a literacy rate of 93.2%. Siaha is the third most literate district, with a literacy rate of 92.9%. Kolasib is the fourth most literate district, with a literacy rate of 92.6%.
The low literacy rate in some districts of Mizoram is due to a number of factors, including poverty, lack of access to education, and the prevalence of child labor. The government of Mizoram is working to improve the literacy rate in all districts of the state by providing free education, building more schools, and providing scholarships to students from poor families.
