Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification. 
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions. 
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros). 
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
