Your answer is option B.
We can see this by multiplying all numbers within A by 4, and then subtracting the corresponding number in B from this.
For example, the top left number in A is 1, 1 × 4 = 4, and the top left number in B is -2, so 4 - -2 = 6, which is the top left number in option B. This pattern applies with the rest of the numbers, which means that option B accurately represents 4A - B.
I hope this helps! Let me know if you have any questions because my explanation was quite strange :)
