The correct statements are-
Erosion occurs even when the mountains are forming. Erosion is the movement of sediments from the broken rocks through the agents like gravity, wind, water and others. It is a constant process occurring even while the mountains are forming. It is affected by gravity.
When new mountains or plateaus form, the cycle starts over. Weathering is the breakdown of rocks by the weathering agents. These sediments move due to the process of erosion. A new sediment may be dropped nearby or in a new place by the process of deposition. Weathering, erosion and deposition occur together as a cycle and have almost leveled the land surface.
Weathering, erosion and deposition have almost leveled earth’s surface. These three processes occur as a cycle and have almost leveled the land surface.

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.
