Answer:

d . a and b are correct

Explanation:

The law of superposition allows us to determine the age of rock layers and also that of the fossils within them.

The law of superposition states that "in an undeformed sequence of strata, the oldest rock layer is at the bottom and the youngest is on top".

  • Using this law, geochronologists can determine the relative ages of rock layers.
  • The youngest layer will be found on top.
  • The oldest at the bottom of the sequence.
  • The arrangement of the layers and the fossils there in can also tell us about the ages of the fossils themselves.
