When a monochromatic beam of light, when a light passes through a high frequency and the propagating directions are polarized along with, when the directions get polarized.
In the above stated situation, the appropriate answer to the question, that which one shall be acceptable form of the magnetic field, the answers is 'a'.

Hey dear,
● Answer-
Acceptable form of magnetic field is -kE / C [(i - j)/√2] cos[10^4(i - j)/ r√2-(3×10^12) t]
● Explaination-
# Given-
v = 3/2π × 10^12 Hz
n̂ = (i + j) / √2
# Solution-
Let i, j & k be unit vectors along x-axis, y-axis & z-axis.
Direction of polarized light beam-
= n̂ × k
= (i + j) / √2 × k
= (i × k) / √2 + (j × k) / √2
= (i - j) / √2
Therefore,
acceptable form of magnetic field = -kE / C [(i - j) / √2] cos[10^4(i - j) / r√2-(3×10^12) t] .
Hope this is useful...
