Answer:
The answer to your question is the letter B
Explanation:
Data
 | 5 0 | | 2 - 1 |
 | 3 -5 | | 2 - 2|
Process
1.- This is the product of two matrices 2 x 2 so the result will be a 2 x 2 matrix.
- Multiply the first row of the first matrix by the first column of the second matrix.
-Multiply the first row of the first matrix by the second column of the second matrix.
- Multiply the second row of the first matrix by the first column of the second matrix.
-Multiply the second row of the first matrix by the second column of the second matrix.
 | 5 0 | | 2 - 1 | | (5 x 2) + (0 x 2) (5 x -1) + (0 x -2) |
 | 3 -5 | | 2 - 2| = | (3 x 2) + (-5 x 2) (3 x -1) + (-5 x -2)|
 = | 10 + 0 -5 + 0 |
 | 6 - 10 -3 + 10|
 = | 10 - 5 |
 | -4 7|
