Answer:
Layer D
Explanation:
The rock layer with remains of organisms least similar to present day form can be found in Layer D.
Since layer D is the oldest layer, it will contain the oldest fossil in the undisturbed sequence.
This is because of the principle of fossils and fauna succession.
The principle states that "fossils and fauna succeed on another in a definite order".
- Therefore, the oldest rock layer should contain the oldest fossil which is layer D.
- Layer A is the youngest layer and its fossils will be very similar to those of present day.
- So, the older a rock layer, the more farther it will be in resemblance to present day organisms.
Option D which denotes layer D is the right choice.
