Answer: (A)

Verified step by step guidance

1. Understand the process of fertilization: A zygote is formed when a sperm cell fertilizes an egg cell. Normally, this zygote travels down the fallopian tube to the uterus for implantation.
2. Identify the location of implantation: In a typical pregnancy, the zygote implants in the lining of the uterus. However, if the zygote implants in the fallopian tube or ovary, it is considered abnormal.
3. Define ectopic pregnancy: An ectopic pregnancy occurs when the zygote implants outside the uterus, most commonly in the fallopian tube. This is a medical emergency as it can cause complications.
4. Differentiate from other conditions: A molar pregnancy involves abnormal growth of placental tissue, while a miscarriage is the loss of a pregnancy. Neither involves implantation in the fallopian tube or ovary.
5. Conclude the implications: Recognize that an ectopic pregnancy requires medical intervention to prevent serious health risks to the individual.
