The peak values of electric field E and magnetic field B in an electromagnetic wave can be found using the following equations:

E_peak = √(2I/ε)
B_peak = √(2I/μ)

where I is the intensity of the wave, ε is the permittivity of free space, and μ is the permeability of free space.

Substituting the given values, we get:

E_peak = √(2 x 1340/8.85 x 10^-12) = 1010 V/m
B_peak = √(2 x 1340/4π x 10^-7) = 3.35 x 10^-16 T

Therefore, the best choice is B, with peak values of E = 1010 V/m and B = 3.35 x 10^-16 T.
