Solution

The correct option is C Sedimentary
Fossils are most commonly found in sedimentary rocks. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remnants. Often these fossils may only be visible when studied under a microscope. Dead organisms in nature are quickly removed by scavengers like bacteria, rotting and erosion, but sedimentation can contribute to exceptional circumstances where these natural processes are unable to work, causing fossilisation. The chance of fossilisation is higher when the sedimentation rate is high (so that a carcass is quickly buried), in anoxic environments (where little bacterial activity occurs) or when the organism had a particularly hard skeleton. Well-preserved fossils are relatively rare. Thus, option C is correct and other options are wrong.
