Which term could be put in the blank to create a fully simplified polynomial written in standard form?8x3y2−_____+3xy2−4y3

The blank must keep the polynomial in standard form and avoid creating like terms. The term x²y² has degree 4, so it fits after 8x³y² and before the degree-3 terms 3xy² and −4y³. Choice C would combine with 3xy², and choice D is another y³ term, so either would prevent the polynomial from being fully simplified.
