Parity is defined as delivery of an infant who is alive. Which option matches this definition?

• A. Number of pregnancies
• B. Number of abortions
• C. Number of viable pregnancies
• D. Delivery of an infant who is alive

Answer: (D)

Parity counts how many times a woman has delivered a live infant. This focuses on completed pregnancies that reached birth with the baby alive, so the option describing delivery of a live-born infant matches the definition. The other ideas refer to the total number of pregnancies (gravidity) or to pregnancies ended by abortion, which do not reflect live births. In short, parity tracks births of living infants, making the live-delivery description the correct match.
