ans is none of the above.
Because the wave is travelling in Z direction.
If TM there will be x and y components but there is no x component of magnetic field and there may be exists of y component and electric field in z direction.
If TE there will be x and y components and magnetic field in z direction. Given electric field in x direction but there may be y component of electric field and z component magneticfield also.
So we can't justify the answer by taking one component of wave.

find the electric field of both charges, but why are they added
together? Because there’s other examples I have encountered where
you subtract them instead
