Answer:
D.) Polynomial
Step-by-step explanation:
A monomial is an expression with only one term (variable/coefficient),
A binomial has two, as well as orders of operations,
A trinomial has three,
But a polynomial has more than three.
This expression has four separate terms, including two different variables, a constant (a number without variables), and a (exponent and) variable with an exponent.
Therefore, this expression is a polynomial
