Where does fertilization occur? A. Uterus B. Cervix C. Ovary D. Uterine tubes

Fertilization typically occurs in the D. Uterine tubes, also known as the fallopian tubes. Here's a step-by-step explanation:

1. Ovulation: Each month, during a woman's menstrual cycle, an egg is released from an ovary in a process called ovulation.

2. Travel of the egg: The egg then travels down the fallopian tube towards the uterus.

3. Fertilization: If sperm are present in the fallopian tube at this time, they may meet the egg and fertilize it. This is the process of fertilization.

4. Implantation: The fertilized egg (now called a zygote) continues down the fallopian tube to the uterus, where it implants into the uterine wall and begins to grow.

So, the correct answer to your question is D. Uterine tubes.
