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

950
970
990
1010

The correct answer is (b) 970.

The sex ratio in Odisha is 970 females per 1000 males. This means that for every 1000 males in Odisha, there are 970 females. This is slightly higher than the national average of 940 females per 1000 males.

There are a number of factors that contribute to the sex ratio in Odisha. One factor is the practice of female infanticide, which is the killing of female babies. Female infanticide is illegal in India, but it is still practiced in some parts of the country, including Odisha. Another factor is the preference for sons over daughters. In some cultures, sons are seen as being more valuable than daughters. This can lead to families aborting female fetuses or neglecting their female children.

The sex ratio in Odisha is a serious problem. It has a number of negative consequences, including a shortage of women in the workforce, an increase in crime, and a decrease in the quality of life for women. The government of Odisha is working to address the problem of female infanticide and the preference for sons over daughters. However, it is a complex problem that will take time to solve.
