The correct answer is (c) 1000:933.
The sex ratio in India is the number of females per 1000 males. According to the provisional figures of the 2011 Census, the sex ratio in India is 933 females per 1000 males. This means that for every 1000 males, there are 933 females in India.
The sex ratio in India has been declining over the past few decades. In 1991, the sex ratio was 927 females per 1000 males. This decline is due to a number of factors, including female infanticide, sex-selective abortion, and the preference for sons in Indian society.
The decline in the sex ratio is a serious concern, as it has a number of negative consequences for the country. For example, it can lead to a shortage of women in the workforce, which can impact economic growth. It can also lead to an increase in crime and violence against women.
The government of India has taken a number of measures to address the issue of declining sex ratio. These measures include awareness campaigns, stricter laws against female infanticide and sex-selective abortion, and incentives for families to have more daughters.
However, these measures have not been successful in reversing the trend of declining sex ratio. More needs to be done to address this issue, which is a serious threat to the future of India.
The other options are incorrect because they do not represent the actual sex ratio in India.
