The correct answer is option 3, Mizoram. Mizoram has the highest literacy rate among the given states. Literacy rate refers to the percentage of people in a specific age group who can read and write. In Mizoram, a large proportion of the population is literate, which indicates a higher level of education in the state.
Option 1, Goa, option 2, Karnataka, and option 4, Himachal Pradesh, are not the correct answers. While these states may have relatively high literacy rates, they are not the highest among the given options.
It is important to note that literacy rates can vary significantly across different states in India due to various factors such as educational facilities, socio-economic conditions, and government initiatives.
