Answer

Choice C.

Work Step by Step

Equation 22-8 shows that the intensity is proportional to the product of the E and B amplitudes. Equation 22-2 shows that the field amplitudes are proportional to each other. If the intensity doubles, then the E and B fields each increase by the same factor, $\sqrt{2}$.
