I’m very confuse on this problem do u mine helping a brother out

Answer:
B
Step-by-step explanation:
So, basically you just need to simplify the answers and see which one simplifies to -3/4^4
so, -3/4 as a decimal is -.75 you would then bring that to the 4th power, you get -.3164...
if you plug the answers into a calculator you will find that answer B will be the correct answer because it equates to -.3164
