Identify a true statement related to the following matrix \(A\). \[ A = \left (\array{ 2& 4 & -3& 7\cr 9 & -5 & -1 & 8 \cr 11& 0 & 8& 12 \cr -7 & -8 & 1& 13 \cr 9& 10 & -6& 2 } \right ) \]
\(A\) is a \(5\times 4\) matrix and \(a_{(2,\, 3)} = -1\).
\(A\) is a \(5\times 4\) matrix and \(a_{(2,\, 3)} = 0\).
\(A\) is a \(4\times 5\) matrix and \(a_{(2,\, 3)} = 0\).
\(A\) is a \(4\times 5\) matrix and \(a_{(2,\, 3)} = -1\).
