Which term refers to developmental anomalies found at birth?

The correct choice is that the term referring to developmental anomalies found at birth is both abnormalities and malformations.

Developmental anomalies encompass a broad range of issues that can arise during the development of a fetus, which can lead to physical differences evident at birth. The term "abnormalities" is a general term that includes any deviations from the normal structure or function which can be congenital (existing at birth). "Malformations" specifically refer to structural anomalies in the body that occur during development and lead to improper formation of organs or body parts.

Since both terms accurately describe conditions that are present at birth, selecting both provides a comprehensive understanding of the various types of developmental anomalies. Therefore, answering with both terms encapsulates the entirety of the concept more fully than selecting just one term would.
