Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
The choices can be found elsewhere and as follows:
a. Increased temperature and pressure
b. Melting and crystallization
<span>c. Exposure and weathering </span>
<span>d. All of the above
</span>
I believe the correct answer is option C. It would be Exposure and weathering that would cause an igneous rock to become soil. <span>Weathering breaks rock down into small particles which are carried away by erosion and deposited somewhere, sometimes creating very verdant soils. </span>
