Consider the network with adjacency matrix A given by 0 0 1 0 0 0 0 0 A = 1 0 0 0 0 0 0 0 0 1 0 1 1 0 0 1 0 With the convention used in the course the in-degree distribution is: Select one: O a. Pin(0) = 1, Pin(1) = 3, Pin(2) = 1, Pin(3) = 1 b. Pin(O) = 1/5, Pin(1) = 2/5, Pin (2) = 2/5, Pin(3) = Pin(4) = 0 O c. Pin(O) = 1/5, Pin(1) = 2/5, Pin(2) = 1/5, Pin(3) = 0 d. Pin(O) = 0, Pin(1) = 4/5, Pin(2) = 1/5, Pin(3) = Pin(4) = 0
