Answer:
Option B is correct
Step-by-step explanation:
To subtract matrix A from matrix B which has the same size as matrix A, you find the pair corresponding elements (which share the same position in matrix) and perform the subtraction.
As shown in picture:
C = A - B
= [3-(-1) 2-0; -4-(-5) 6-2; 7-4 5-9]
= [4 2; 1 4; 3 -4]
=> Option B is correct
