Which term is defined as the ending of a pregnancy?

• A. The implantation of embryo
• B. The cessation of fetal movement
• C. The birth of a child
• D. The ending of a pregnancy

Answer: (D)

The idea being tested is the terminology for ending a pregnancy. The ending of a pregnancy is described by the term abortion (also called termination of pregnancy). Among the options, the one that literally says “the ending of a pregnancy” matches this definition most directly, making it the best choice. The other items refer to different moments or signs in pregnancy: implantation marks the start, cessation of fetal movement is a sign rather than a definition of the end, and birth is the delivery event that ends gestation but isn’t the term used to define the ending.
