In the human being, normally in which one of the following parts, does the sperm fertilize the ovum?

Cervix
Fallopian tube
Lower part of uterus
Upper part of uterus

The correct answer is: B. Fallopian tube.

The fallopian tubes are two narrow tubes that connect the ovaries to the uterus. The ovaries are the female reproductive organs that produce eggs. The uterus is the organ in which a fertilized egg implants and develops into a baby.

When a woman ovulates, an egg is released from one of her ovaries. The egg travels down the fallopian tube to the uterus. If sperm are present in the fallopian tube, they can fertilize the egg. Fertilization usually occurs within 12 to 24 hours after ovulation.

Once the egg is fertilized, it implants in the lining of the uterus. The fertilized egg then begins to divide and grow into a baby. The baby will remain in the uterus until it is born.

The cervix is the lower part of the uterus that connects the uterus to the vagina. The lower part of the uterus is the part of the uterus that is closest to the vagina. The upper part of the uterus is the part of the uterus that is closest to the fallopian tubes.

Sperm cannot fertilize an egg in the cervix or the lower part of the uterus. Sperm can only fertilize an egg in the fallopian tube.
