The correct options are
A AB≠BA in general
B The product of two non zero matrix may also be a zero matrix.
C A I = I A =A(where, I=identity matrix)
→In general, AB≠BA as multiplication inmatrices is not commutative.
→The product of two non zero matrices may also be a zero matrix−(0101]×(2000]=(0000]→A I =(2000]×(1001]=(2000]=A=(1001]×(2000]= I A
