The correct answer is (a) 972.
The sex ratio is the number of females per 1000 males in a population. As per Census-2011, the sex ratio of Uttarakhand State is 972. This means that there are 972 females for every 1000 males in the state.
The sex ratio in Uttarakhand has been increasing over the years. In 1991, the sex ratio was 934. It increased to 946 in 2001 and 963 in 2011. This increase in the sex ratio is due to a number of factors, including a decline in female infanticide, an increase in the age at marriage for women, and an increase in the number of women in education and employment.
The high sex ratio in Uttarakhand is a positive sign for the state. It indicates that women are valued and respected in the society. It also means that the state has a large pool of potential workers and entrepreneurs. However, the state needs to do more to ensure that all women have equal opportunities to participate in all spheres of life.
