The question is incomplete as it does not have the option which are
- superposition
- paleomagnetism
- fluorine analysis
- geolayering
Answer:
Superposition
Explanation:
In calculating the relative age of the fossils, the paleontologists use the principle or law of superposition.
The law of superposition states that the rock has layers in which one layer is deposited over another layer. Each layer of these layers is older than the layer which is present at the top of this layer.
Therefore, this method can be used to determine the relative age of the fossils like in the given case, the species A found in the lower layer than the species B because the species B is present in the top layer.
Thus, the superposition is correct.

Stem cells begin to transfor into different types of cells in the human body in a process known as cell differentiation.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types.
Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.
