The false statement is - C. It is common for a plant or animal to fossilize when it dies.
In for a plant or animal to fossilize, there have to certain conditions that will enable that process, or rather preservation. That is not the case usually, and considering the amount of animals and plants that existed, and even more the ones that existed in the geological past, the amount of fossils is extremely small. If it was common for the plants and animals to be fossilized, even 1 out of 1,000, than we would have been seeing and finding fossils pretty much on every spot of the planet, but that is not the case.
The following are the four essential zones in earth's interior:
1. Crust- is the peripheral strong shell of a rough planet or normal satellite, which is artificially unmistakable from the basic mantle.
2. Mantle - is a silicate rough shell with a normal thickness of 2,886 kilometers (1,793 mi). The mantle makes up around 84% of Earth's volume.
3. outer core - Its external limit lies 2,890 km (1,800 mi) underneath Earth's surface.
4.inner core - is the Earth's deepest part and as per seismological reviews, it has been accepted to be essentially a strong ball with a span of around 1,220 kilometers (760 miles), which is around 70% of the Moon's range.
