Let M and n be two `3xx3` matrices such that `MN = NM`.
Further, If `Mne N^(2) and M^(2) = N^(4)`, then

A

determinant of `(M^2=N^4)` is 0

B

there is a `3xx3` non-zero matrix U such that:
`(M^2+MN^2)` U is the zero matrix.

C

determined of `(M^2+MN^2)ge1`

D

for a `3xx3` matrix U, if `(M^2+MN^2)` U equals the zero matrix, then U is the zero matrix.
