By using multiplication of matrices, we know that no of columns of A should be equal to no of rows of B. so the order of matrix AB is1*1. here B is a identity matrix . and any matrix multiplied to identity matrix I is the matrix itself. hence AB=A.

Just simply multiply row with column (1×1 + 2×0 + 3×0) (1×0 + 2×1 + 3×0) (1×0 + 2×0 +3×1) = [ 1 2 3 ] hence option 'd' is correct .
