The correct answer is: d) Varies greatly across districts.
The sex ratio in Assam is 950 females per 1000 males, which is lower than the national average of 940 females per 1000 males. However, the sex ratio varies greatly across districts in Assam. For example, the sex ratio in the district of Goalpara is 924 females per 1000 males, while the sex ratio in the district of Karimganj is 976 females per 1000 males.
There are a number of factors that contribute to the variation in sex ratio across districts in Assam. One factor is the practice of female infanticide. Female infanticide is the practice of killing female babies at birth or shortly after birth. It is a common practice in some parts of India, including Assam. Another factor that contributes to the variation in sex ratio across districts in Assam is the migration of men. Men are more likely to migrate from rural areas to urban areas in search of work. This can lead to a shortage of men in rural areas and an excess of men in urban areas.
The variation in sex ratio across districts in Assam has a number of consequences. One consequence is that it can lead to social problems, such as an increase in crime and violence. Another consequence is that it can lead to economic problems, such as a shortage of workers in certain sectors of the economy.
