 Consider the network below:

ABCDE

What is the Pearson degree correlation coefficient (r) for this network using Mark Newman's definition?

A. r = 0, since the average degree of every node’s neighbors equals ⟨k⟩.

B. r = -2/3, indicating the network is assortative.

C. r = +2/3, indicating the network is disassortative.

D. r = -1/2, indicating the network is assortative.

E. None of the above.
