Which option has degree 11 and coefficient of x^10 equal to 0?

Answer and explanation

Correct answer: 7x^11 − 5x^9 + 1

To satisfy both conditions, inspect the highest exponent and check whether an x^10 term is present. In option A, the highest exponent is 11 and its coefficient is 7, so the degree is 11. There is no x^10 term; an absent term has coefficient 0. Thus option A meets both requirements. Option B has degree 11 but contains x^10 with coefficient 1, so it fails the second condition. Option C has no x^11 term and therefore degree 10, while option D has the term x^12 and therefore degree 12. The correct answer is consequently option A, based on both degree and coefficient conditions rather than on only one of them.
