The correct answer is (a) Arunachal Pradesh.
Arunachal Pradesh has the highest sex ratio in India, with 972 females per 1000 males. This is significantly higher than the national average of 940 females per 1000 males. The sex ratio in Arunachal Pradesh has been increasing steadily over the past few decades. In 1991, the sex ratio was 953 females per 1000 males. This increased to 964 females per 1000 males in 2001 and to 972 females per 1000 males in 2011.
There are a number of factors that contribute to the high sex ratio in Arunachal Pradesh. One factor is the practice of female infanticide, which is illegal but still occurs in some parts of the state. Another factor is the high rate of migration of men from other parts of India to Arunachal Pradesh. This migration leaves a surplus of women in the state.
The high sex ratio in Arunachal Pradesh has a number of implications. One implication is that there is a shortage of marriageable men in the state. This has led to an increase in the number of inter-state marriages and to an increase in the number of women remaining unmarried. Another implication is that there is a shortage of labor in the state. This has led to an increase in the number of women working outside the home.
The high sex ratio in Arunachal Pradesh is a complex issue with a number of causes and implications. It is important to understand the factors that contribute to the high sex ratio in order to address the issue effectively.
