Answer:
Place the corpse in an environment where decomposition is slow (such as a swamp or bog).
Step-by-step explanation:
If any living thing gets preserved or its trace remains after a long period of time then a fossil is said to be formed and the process by which it is formed is termed as fossilisation.
There are several factors which affects whether a particular component will get fossilised or not, some of them are :
1. Hardness of the material - the harder the substance the higher the chances of getting fossilized.
2. The environment - whether it causes decay or preservation.
3. Speed of burial - the faster the burial the higher the chances of fossilisation .
Therefore, keeping these factors in mind to increase the probabilty of fossilization the corpse should be placed in environemnt where there is slow decomposition and such environment is provided in places such as bogs or swamps.
