As per the 2011 Census data, the child sex ratio (number of girls per 1,000 boys in the age group of 0-6 years) varies across states in India. The states are ordered from the lowest to the highest child sex ratio as follows:
Thus, the correct order from lowest to highest child sex ratio is (A), (B), (C), (D).
To order Indian states by child sex-ratio (females per 1000 males in the 0-6 age group) from lowest to highest based on 2011 data, consider the following approximate ratios:
Arranging these states by their child sex-ratio in ascending order yields:
The sequence is thus Haryana, Punjab, Tamil Nadu, Sikkim.
