Answer:
A. Quadratic trinomial
Step-by-step explanation:
You can easily eliminate B and C because trinomial means there are three terms. B has monomial (one term) and C has binomial (two terms).
Now you have A and D. D is cubic which means the first term (4x²) would have to be cubed (4x³). Quadratic means it is squared.
