Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.
What is big bang theory?
The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

Answer:
The correct answer is - it is essential to produce red blood cell and development of the spinal cord and brain.
Explanation:
Folic acid is natural form of vitamin B9 which is essential for producing red blood cells therefore the level of this vitamin should be in proper amount as in fetuses it is crucial for the various organs to develop,
The neural tube, spinal cord, and brain growth requires appropriate amount of folic acid in pregnant women. Low level of this vitamin can leads to the risk of various disease in baby
Thus, the correct answer is -it is it is essential to produce red blood cell and development of the spinal cord and brain.
