Final answer:
An ectopic pregnancy occurs when the embryo implants outside the uterus, which can lead to significant health risks. The correct answer to the question is 'c) ectopic.'
Step-by-step explanation:
A pregnancy outside the uterus is described as an ectopic pregnancy. Most embryos implant within the uterine cavity where they can grow and develop. However, in some cases, the embryo implants elsewhere, such as in the uterine tube for a tubal pregnancy, in the ovary for an ovarian ectopic pregnancy, or even in the abdominal cavity. These situations can lead to severe health risks for the pregnant individual, as areas outside the uterus are not equipped to support a growing fetus. This is in contrast to disorders like placenta previa, where the embryo plants in a suboptimal location within the uterus itself. The correct answer to the original question is 'c) ectopic.'
