This question is about state level findings from the 1986-89 National Programme for Control of Blindness (NPCB) survey, one of India's earliest large blindness prevalence surveys.
- Jammu and Kashmir: Recorded a blindness burden in the survey, but not the highest among the states listed.
- Orissa: Also showed a meaningful blindness prevalence, again lower than the top state.
- Bihar: Similarly affected, but not the highest ranked state in this survey.
- Uttar Pradesh: This state showed the highest prevalence of blindness among the options, matching what the 1986-89 NPCB survey data recorded.
Large, populous northern states with limited eye care access at the time tended to show a higher blindness burden, and Uttar Pradesh stood out with the highest rate among the choices given here.
Let's summarize:
- The 1986-89 NPCB survey found real state to state differences in blindness prevalence.
- Uttar Pradesh recorded the highest prevalence among these four states.
So the correct answer is Uttar Pradesh.
