Remember that polynomials are closed under addition, subtraction, and multiplication, but they are not closed under division. The only division you have there is B; therefore the correct answer is B.
A.
. The result is still a polynomial; therefore, answer A is incorrect.
B.
with a remainder of 26. The result is not a polynomial anymore; therefore, B is the correct answer.
C.
. The result is still a polynomial; therefore, answer C is incorrect.
D.. The result is still a polynomial; therefore, answer D is incorrect.
