You were posted at a PHC catering to a population of 1,20,000. In the year 2006, a total number of 2500 liver born babies were delivered. Number of children dying under one year of age during 2006 was 150. What is the infant moality rate of this population ?

**Core Concept**
The infant mortality rate (IMR) is a crucial public health indicator that measures the number of deaths of infants under one year of age per 1,000 live births in a given year. It reflects the quality of healthcare, sanitation, and overall well-being of a population.

**Why the Correct Answer is Right**
To calculate the IMR, we use the formula: IMR = (Number of deaths under one year of age / Number of live births) x 1000. Given that 2500 liver born babies were delivered and 150 children died under one year of age, we can plug these numbers into the formula. IMR = (150 / 2500) x 1000 = 60.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not provide a clear calculation or a number that matches the formula for IMR.
* **Option B:** This option is incorrect because it does not take into account the number of live births, which is essential for calculating IMR.
* **Option C:** This option is incorrect because it does not provide a valid calculation or a number that matches the formula for IMR.
* **Option D:** This option is incorrect because it does not provide a clear calculation or a number that matches the formula for IMR.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that IMR is a sensitive indicator of a population's overall health and well-being. A high IMR can indicate poor healthcare infrastructure, inadequate maternal and child care, and other underlying social determinants of health.

**Correct Answer:** A. 60.
