The correct answer is: a) Lower than the national average.
The sex ratio in Manipur is 939 females per 1000 males, which is lower than the national average of 940 females per 1000 males. This means that there are fewer females than males in Manipur.
There are a number of reasons for this, including female infanticide, gender-selective abortion, and the practice of dowry. Female infanticide is the practice of killing female babies at birth, often because they are seen as a burden to their families. Gender-selective abortion is the practice of aborting female fetuses, often because parents prefer to have sons. Dowry is a payment that is made by the bride’s family to the groom’s family at the time of marriage. In some cases, the demand for dowry can be so high that it can lead to families abandoning or killing their daughters.
The sex ratio in Manipur is a serious concern, and it is important to address the root causes of this issue. This includes raising awareness about the problem, providing support to families who have been affected by it, and enacting laws to protect women and girls.
Option b) is incorrect because the sex ratio in Manipur is lower than the national average.
Option c) is incorrect because the sex ratio in Manipur is not equal to the national average.
Option d) is incorrect because the sex ratio in Manipur does not vary greatly across districts. The sex ratio is relatively consistent across the state, with the exception of a few districts where it is slightly lower.
