Maternal Mortality Ratio is expressed per 100,000 live births primarily to: MCQ with Answer and Explanation

Maternal Mortality Ratio is expressed per 100,000 live births primarily to:
A. Simplify international comparisons
B. Align with infant mortality rate units
C. Avoid very small decimal values for rare events

Answer: Option C
Solution (By JKExamLibrary)
Maternal deaths are relatively rare; using a base of 100,000 live births yields manageable numbers (e.g., 100-500) instead of tiny decimals (0.001-0.005), enhancing readability and comparison.
