- ACervix
- BFallopianCorrect
- CLower part of uterus
- DUpper part of uterus
Explanation
The correct answer is B because fertilization occurs in the fallopian tube, which connects the ovaries to the uterus. After ovulation, the ovum is released into the fallopian tube where it meets the sperm. Specifically, fertilization usually takes place in the wider section of the tube called the ampulla. The fertilized egg then travels down to the uterus for implantation. Options A, C, and D are incorrect because the cervix and uterus are sites for sperm passage or embryo development, not the initial union of sperm and egg.
