According to the principle of faunal succession, what must be true of the fossils on a layer below?

younger than the fossils above

older than the fossils in the layer above

the same age as the fossils in the layers above

identical to the fossils in the layers above

older than the fossils in the layer above

Explanation:

The principle of the faunal succession describes that the fossils below must be of an older structure and hence in order to succeed the upper fossils must contain the layer of newer species that adds up to the geologic or geological diverse layered structure of rocks from below.  In order to identify them are diagnostic species, those that are on the fastest rate of turnover and are widely distributed in this study are also called biostratigraphy i.e science of dating rocks by the comparison of fossil the ancient plants and animals. Hence the classification of various taxas is possible.
