The correct answer is (c). The sex ratio in India in 2001 was 933 females per 1000 males.
The sex ratio is the number of females per 1000 males in a population. It is an important indicator of the status of women in a society. A low sex ratio indicates that there are fewer women than men in the population, which can be due to a number of factors, including female infanticide, sex-selective abortion, and gender-based violence.
The sex ratio in India has been declining steadily since the early 20th century. In 1901, the sex ratio was 972 females per 1000 males. By 2001, it had declined to 933 females per 1000 males. This decline is due to a number of factors, including the increasing use of sex-selective abortion, the preference for sons over daughters, and the increasing practice of female infanticide.
The declining sex ratio in India is a serious concern. It has a number of negative consequences, including a shortage of women in the workforce, an increase in the number of elderly people, and an increase in the crime rate. The government of India has taken a number of measures to address the issue of the declining sex ratio, including the introduction of laws against sex-selective abortion and the promotion of education for girls. However, more needs to be done to address this issue.
