Identify a true statement related to the following matrix \(A\). \[ A = \left (\array{ -2& 3 & 10& 5 & -5\cr 6 & 11 & -7 & 2 & -3 \cr -7& 15& -6& 2 & 4\cr -8 & 1 & 13 & -5 & 0 } \right ) \]
\(A\) is a \(4\times 5\) matrix and \(a_{(3,\, 2)} = 15\).
\(A\) is a \(4\times 5\) matrix and \(a_{(2,\, 3)} = 15\).
\(A\) is a \(5\times 4\) matrix and \(a_{(3,\, 2)} = -7\).
\(A\) is a \(5\times 4\) matrix and \(a_{(3,\, 2)} = 15\).
