Answer:
Layer D
Explanation:
Since Layer D and Layer C are on the same elevation, we could assure that a fossil is found on these layers while Layer B, A, and F are above Layer C in which is less likely to find a fossil on these layers than on Fossil D.
Gray matter consists of the <u>unmyelinated axons</u> of neurons.

The outer layer of the brain consists of the grey matter and white matter. The grey matter gets its name by the pinkish grey colour obtained by the greyish colour of the neurons and the red colour from the capillaries.
The grey matter consists of the dentrites, axons and cell bodies and this is essential for memory, attention and learning.

Explanation:
Complication to Phylogenetic inference is most likely to be widespread in a group of species that have undergone an evolutionary radiation because of Great variability of the rates of molecular evolution Incomplete lineage sorting.

option c is correct.
