Answer 1

The correct option is C

Oviduct

The correct option is C.

Explanation of the correct option:

1. In humans, fertilization takes place in the fallopian tube.
2. The fallopian tube is also known as the oviduct.
3. So the early development of the fertilized egg takes place in the fallopian tube.
4. The main functions of the fallopian tube are the transport of sperm cells to the egg, providing suitable conditions for fertilization, and transport of the egg from the ovary to the uterus.
5. Sperm fuse with egg to form zygotes in the ampullary isthmic junction of the fallopian tube.

Explanation of the incorrect options:

Option A:

1. Every female has a pair of ovaries. They are female reproductive glands that produce and store eggs.
2. The eggs are released from the ovary to the fallopian tube in every menstrual cycle during ovulation.
3. They release hormones that control the pregnancy.

Option B:

1. The testis is the male reproductive part. They are the male primary sex organs.
2. They produce sperms and release the male hormone testosterone.
3. Sperm reach the female reproductive tract during copulation.
4. Sperm fuse with zygotes in the female reproductive system.

Option D:

1. The uterus is the female reproductive organ.
2. It is also known as the womb.
3. The fertilization occurs in the fallopian tube.
4. The uterus receives the embryo at the morula stage.
5. Further development of the embryo takes place in the uterus.

Final answer: In humans, the development of the fertilized egg takes place in the oviduct.
