The average occipital-frontal circumference (OFC) of a newborn at 40 weeks gestational age is:

Explanation:
Head circumference around the largest head circumference measurement (occipito-frontal) reflects how the skull and brain have grown by term. At 40 weeks, the average OFC is about 35 cm, with a typical range roughly 32–38 cm. So the value closest to this average is 35 cm. A measurement of 32 cm is on the lower end, 38 cm on the higher end, and 40 cm is above the usual term range. OFC helps screen for abnormal brain growth when evaluated alongside other growth measurements.
