In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .
