Is diagonalizable if and only if let a e m,.(c). a) a-0. then (o b) a-i. e) n-2. d) none of the other three options

PFA Minimal polynomial of M is LCM of minimal polynomial of the blocks. That's why m(M) is zero. Rest is easy , suppose there is another polynomial p which annihilate M then it sh...

option a

Option A is correct.

zero matrix is always diaganolizable(infact only null matrix that is diagonalizable is null matrix) hence a is correct. Suppose n=1 and then A is 1,then check the eigen values ,it ...

see attached, option a Is correct
