Answer:
The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example
Explanation:
The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.
