Answer:

(a)

Explanation:

Add A to both sides of the equation:

X -A +A = B +A

X = B + A

The sum of the two matrices is the matrix that is the sum of corresponding terms.

x11 = B11 +A11 = -9+2 = 7

x12= B12 +A12 = 5-7 = -2

These calculations are sufficient to match the answer with choice (a).
