Pregnancy in which the fertilized egg attempts to develop outside of the uterus.

• A. Normal pregnancy
• B. Twin pregnancy
• C. Ectopic pregnancy
• D. Molar pregnancy

Answer: (C)

Fertilized egg attempting to develop outside the uterus describes an ectopic pregnancy. In this situation implantation happens outside the uterine cavity—most commonly in the fallopian tube—so the pregnancy cannot progress normally and can lead to life-threatening internal bleeding if the tissue ruptures. This differs from a normal pregnancy, which implants in the uterine lining; a twin pregnancy is still typically intrauterine; and a molar pregnancy involves abnormal growth of placental tissue inside the uterus, not outside it.
