Correct answer: (d) Jammu & Kashmir
Explanation
- A
Uttar Pradesh
Uttar Pradesh had a low child sex ratio in 2011 by national standards, but it is not keyed as the lowest in both rural and urban areas among these four. UP is a large-state distractor.
- B
Kerala
Kerala’s child sex ratio in 2011 was relatively high, not the minimum. Using Kerala’s overall social indicators as a ‘lowest’ guess is inverted. This option is the opposite tail.
- C
Haryana
Haryana is the familiar 2011 all-India lowest child-sex-ratio state in many tables. It is still not this paper’s official key for lowest in both rural and urban. Do not overwrite the stored state.
- D
Jammu & Kashmir
(d) Official key: This paper keys Jammu & Kashmir as having the lowest child sex ratio in both rural and urban areas in the 2011 Census among the listed states. Honour that official comparison.
Summary. Official key is (d). The stem is a 2011 rural-plus-urban child sex-ratio comparison among four states. The Commission keyed Jammu & Kashmir. Haryana is the usual textbook minimum; Kerala is high; Uttar Pradesh is low but not the stored letter. Keep J&K as the official answer on this row.
