Area of a Circle

Chris has a passion for spaghetti. Plate A has a radius of $4x - 2$, plate B has a radius of $2x + 1$, plate C has a radius of $x + 2$, and plate D has a radius of $x^2 + 1$. If the biggest plate has an area of $\pi(4x^2 + 4x + 1)$, which plate would Chris most likely use? (Assume Chris is going for the biggest plate possible, and the plates are circles with four different radii.)
