correct option should be d.
because complex roots always occur in pairs. hence eigen values will be i, -i , 0.

because complex roots always occur in pairs. i.e if one root is a+ib another should be a-ib.
here if one root is i another should be -i.

Self doubt: what are eigen values of resultant matrix when add two matrices?
if eigen values of matrix A = a,b,c if eigen values of matrix B = x,y,z then is it holds every time that eigen value of A+B = a+x, b+y, c+z ? please give some reference to you answer, thankyou.
