Specify how the rank of the matrix \(A\) changes depending on the value of \(t\), where
\[
A=\left (\array{
3& -2& 1&-4\cr
-6& 4& -2&8\cr
0& t& 0&t} \right ).
\]
If \(t=0\), the rank is \(1\), otherwise the rank is \(2\).
If \(t=0\), the rank is \(1\), otherwise the rank is \(3\).
If \(t=0\), the rank is \(2\), otherwise the rank is \(1\).
If \(t=2\), the rank is \(3\), otherwise the rank is \(1\).
