Answer:
(C) amniotic fluid
Explanation:
Amniotic fluid is the fluid that surrounds the baby during the nine months of pregnancy, filling the amniotic sac. This fluid has numerous functions that are extremely important for the development of the unborn baby. Among these functions is the maintenance of a constant temperature inside the womb, so the temperature the baby receives is not influenced by the mother's body temperature.
Since most amniotic fluid is composed of water, the amniotic sac is also known as the water pocket.
