A data center has 10 backup servers. Each pair of servers can establish a direct synchronization link independently with probability $1/9$.

Question:
Which statement is correct about this network?

A. The expected degree is $8/9$, so the network is below the critical point.
B. The expected degree is $1$, so the network is exactly at the critical point.
C. The expected degree is $10/9$, so the network is above the critical point.
D. The expected number of links is $10$, so the network is above the critical point.
E. The expected degree is $\mathrm{2,\; so\; the\; network\; is\; far\; above\; the\; critical\; point.}$
