Consider the following statement about a polynomial p(x)p(x) with real coefficients:

(∗)(*) If p(n)p(n) is even for every integer nn, then every coefficient of p(x)p(x) is even.

Which one of the following is a counterexample to (∗)(*)?

Ap(x)=x2+xp(x)=x^2+x
Bp(x)=2x2+4p(x)=2x^2+4
Cp(x)=2x2+xp(x)=2x^2+x
Dp(x)=4x3+2xp(x)=4x^3+2x
