If \( D \) is a determinant of order three and \( \Delta \) is a determinant formed by the cofactors of determinant \( D \); then
(a) \( \Delta=D^{2} \)
(b) \( D=0 \) implies \( \Delta \neq 0 \)
(c) if \( D=27 \), then \( \Delta \) is not perfect cube
(d) if \( D=27 \), then \( \Delta \) is not perfect square
