Correct Answer: A
Solution :
Fossilization is the process of formation of fossils. Fossilizadon would occur when flora and fauna are hurried by natural process like lava of Volcano in the ice, in swamps, in rocks in dessicated deserts etc. The fossils are generally preserved in sedimentary rocks which are formed by the deposition of silt, sand or calcium carbonate over millions of years. Silt deposits give shales, sand gives sandstone and calcium carbonate gives limestone. The most common method of rossilization involves the ultimate conversion of the hard part of body (i.e., bones, teeth, shells etc) to rocks.
