The correct answer is B) 970.
The sex ratio in Karnataka is 970 females per 1000 males. This means that for every 1000 males in Karnataka, 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 can contribute to a skewed sex ratio, including gender-based violence, female infanticide, and sex-selective abortion. In India, there is a long history of preference for sons over daughters. This has led to a number of practices that have resulted in a lower number of girls being born than boys.
In recent years, there have been a number of initiatives aimed at improving the sex ratio in India. These include awareness campaigns, education programs, and changes to the law. However, there is still a long way to go to achieve a truly equal sex ratio.
