Answer:
According to me ..
Step-by-step explanation:
No, this is not true. Take for example the matrix
A=[000
100
000]
which has the property that ever minor's determinant (and thus every co-factor) is zero. (To see why this is, note that ever minor must have a zero row, since there are two zero rows in A and you can't eliminate both when creating a minor)
