What was the length of the longest human baby at birth in centimetres?

The correct answer is based on documented records of human births. The longest human baby at birth measured approximately 76 centimetres. This length is notably longer than average, as the typical range for newborns is around 50-55 centimetres. The reported record of 76 centimetres highlights extraordinary cases of growth, which can be influenced by a variety of factors including genetics and maternal health during pregnancy.

While other options present figures that are significantly higher than documented records, 90 centimetres and 80 centimetres exceed the boundaries of common childbirth measurements. Comparatively, 60 centimetres, though within a reasonable range for a newborn, does not represent the record length cited. Thus, 76 centimetres stands as the correct choice by reflecting a recognized benchmark in human birth statistics.
