All of the following conditions preserve organisms as fossils except

quick burial by sediments

hard parts

protection from scavengers

activities of microorgansims

Last one activites by mircorganism

Option (4)

Explanation: In order to form a fossil, following steps must be taken place-

The dead organism must contain hard parts in their body that are not affected by the decomposers.Immediate burial of organism should take place by the sediments.The body should be covered in such a way that it does not come in contact with the oxygenated environment.The organism's body must must be away from the microorganisms and other scavengers.It would take about a million of years to turn it to a fossil.

Thus, these are the conditions that are required for a dead organism to become fossils after millions of years.

Thus, the correct answer is option (4).
