(D) polynomial of degree $2$ is called a quadratic polynomial.In option $A$,$p(x) = 2 - 4x$ is a linear polynomial (degree $1$).In option $B$,$p(x) = 2x^3 - 1$ is a cubic polynomial (degree $3$).In option $C$,$p(x) = 2x - 5$ is a linear polynomial (degree $1$).In option $D$,$p(x) = 1 - x^2$ is a quadratic polynomial because the highest power of the variable $x$ is $2$.
