Sex ratio is the number of females per 1000 males in a population. It is an important indicator of the social status of women, and the Census of India reports it for every state and district.

The provisional population totals of Census 2011 gave Jharkhand a sex ratio of 947 females per 1000 males, higher than the national figure of 940 in the provisional data. The final census tables later put the state figure at 948, so among the given values 947 is the census figure for the state.

933 is India's sex ratio from Census 2001 and 910 is far below the state's recorded level, so neither applies. 955 is higher than the census count for the state and does not match any official 2011 figure for it.

947 option is correct.
