1(xii)
If matrix A of order 2 × 1 and matrix B of order 2 × 2 are added, then the order of the matrix A + B is:
- (a)2 × 2
- (b)2 × 1
- (c)1 × 2
- (d)A + B is not possible

Given,
A of order 2 × 1
B of order 2 × 2
Since their orders are different, thus matrix A and B cannot be added.
Thus, A + B is not possible.
Hence, option 4 is the correct option.
