**Core Concept**
The perinatal mortality rate (PMR) is a measure of the number of stillbirths and early neonatal deaths per 1,000 total births. It is an important indicator of maternal and child health.

**Why the Correct Answer is Right**
To calculate the perinatal mortality rate, we use the formula: (number of stillbirths + number of early neonatal deaths) / total number of births. In this case, the number of early neonatal deaths is assumed to be equal to the number of neonatal deaths, which is 450. Therefore, the numerator is 2 (stillbirths) + 450 (early neonatal deaths) = 452. The total number of births is 12,450. Now, we can plug these values into the formula to get: (452 / 12,450) x 1000.
