The development of the embryo is also known as embryogenesis. It includes both cell division as well as differentiation. The period until implantation occurs is known as the germinal stage. During this phase active cell division occurs. Leads to the formation of a blastocyst or blastula. The next stage is gastrulation. And later the various embryonic layers are formed. It is further followed by neurulation and organogenesis respectively. Different organs get formed and developed at different stages of pregnancy.
The fifth month of development is characterized by the movement of the fetus within the womb, the first movement shown by the fetus is called quickening. It is also characterized by the development of body hair. At this time, the muscles also start to develop.
Considering the other given options:
A.Third month, the arms, feet, toes, fingers, as well as hands, develop completely. The finer and toenails are starting to grow. The development of reproductive organs also starts. Thus it is not the right option.
B. In the fourth month, the heartbeat of the fetus can be listened to, through a Doppler test. The fingers, as well as toes, get completely formed. Thus it is not the right option.
D. In the sixth month, the fingerprints are formed. The eyes open, and the eyelids get separated. Thus it is not the right option.

The appearance of hair on the head of the foetus and the first movements are important milestones in pregnancy. The correct answer to this question is option B, which is the fifth month.
Explanation:
The development of the foetus during pregnancy is a gradual process that occurs in different stages. Here are some of the key milestones that occur during the fifth month of pregnancy:
1. Foetal movements:
During the fifth month, the foetus begins to move more actively in the womb. These movements may be felt by the mother as "flutters" or "butterflies" in the stomach. As the foetus grows, its movements will become more noticeable and may even keep the mother awake at night.
2. Appearance of hair:
By the fifth month of pregnancy, the foetus will have developed fine hair on its head. This hair is called lanugo and is usually shed before birth. The lanugo helps to regulate the body temperature of the foetus and protect its skin from the amniotic fluid.
3. Development of the nervous system:
During the fifth month, the nervous system of the foetus continues to develop. The brain and spinal cord are becoming more complex, and the foetus is starting to develop its sense of touch, taste, and smell.
4. Growth and development:
By the fifth month of pregnancy, the foetus is about 10 inches long and weighs around 10 ounces. It is starting to look more like a baby, with distinct facial features and limbs that can move independently.
In conclusion, the appearance of hair on the head of the foetus and the first movements are usually observed during the fifth month of pregnancy. This is an exciting time for expectant parents as they begin to feel the presence of their growing baby.
