Which of the following matrix is non singular 

$\begin{array}{l}\left|\begin{array}{ccc}1& -1& 2\\ 3& 2& 1\\ 5& 2& 3\end{array}\right|=(6-2)+1(9-5)+2(6-10)\\ =4+4-8\\ =0\text{ sinqular }\end{array}$

$\begin{array}{l}\left|\begin{array}{ccc}1& 2& -1\\ 3& 1& 2\\ -2& 1& -3\end{array}\right|=1(-3-2)-2(-9+4)-1(3+2)\\ =-5+10-5\\ =0\text{ singular }\end{array}$

$\begin{array}{l}\left|\begin{array}{ccc}2& -3& 1\\ 1& 2& 3\\ -3& 1& -4\end{array}\right|=2(-8-3)+3(-4+9)+1(1+6)\\ =-22+15+7\\ =0\text{ singular }\end{array}$

$\begin{array}{r}\left|\begin{array}{lll}2& 1& 4\\ 3& 2& 1\\ 5& 6& 3\end{array}\right|=2(6-6)-(9-5)+4(18-10)\\ =0-4+32=28\ne 0\text{ non singular }\end{array}$
