- B 1000 live births in the same year ✓
- C 1000 total births (live + still) in the same year
- D 10,000 population
Correct answer: B. 1000 live births in the same year
Explanation
IMR is calculated as (Deaths under 1 year / Live births in the same year) × 1000. It is expressed per 1000 live births (not total births or total population). IMR is a sensitive indicator of socioeconomic development, healthcare infrastructure, and maternal-child health services. India's IMR as per SRS 2021 is approximately 28/1000 live births.
