The sex ratio in Sikkim (females per 1000 males) is:

Among India's lowest
Slightly below the national average
About equal to the national average
Higher than the national average

The correct answer is: c) About equal to the national average.

The sex ratio in Sikkim is 973 females per 1000 males. This is slightly higher than the national average of 940 females per 1000 males. The sex ratio in Sikkim has been increasing in recent years, from 964 females per 1000 males in 2001 to 973 females per 1000 males in 2011. This increase is likely due to a number of factors, including improved healthcare and education for women, as well as a decline in female infanticide.

The sex ratio in India is one of the lowest in the world. This is due to a number of factors, including female infanticide, sex-selective abortion, and neglect of girls. The sex ratio in India has been declining in recent years, but it is still far below the global average of 1000 females per 1000 males.

The sex ratio is an important indicator of gender equality. A high sex ratio indicates that women are valued and respected in society. A low sex ratio indicates that women are not valued and may be discriminated against.
