QUESTION 7

Matrix NN represents the results for a competition involving four teams.
N=[0011100001000110]N=\begin{bmatrix}0&0&1&1\\1&0&0&0\\0&1&0&0\\0&1&1&0\end{bmatrix}
Key: Team P lost to team Q but won against teams R and S.
Using the ranking model N+0.5N2N+0.5N^2, the teams that placed first, second and third respectively are
(A)
P, S and Q.
(B)
P, S and R.
(C)
S, P and Q.
(D)
