Correct Option: A
L(\begin{pmatrix} x_1 & y_1 \ -1 & -6 \end{pmatrix}) m L(\begin{pmatrix} x_2 & y_2 \ -3 & -5 \end{pmatrix})
D = (\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2})
D = (\sqrt{(-3 - (-1)^2 + (-5 -(-6)^2})
D = (\sqrt{(-3 + 1)^2 + (-5 + 6)^2})
D = (\sqrt{(-2)^2 + 1^2})
D = (\sqrt{4 + 1})
D = (\sqrt{5})
