The higher the degree of ionization, the stronger the conductivity
Answer:- The wavelength is
and the right option is D.
Solution:- Wavelength is inversely proportional to the frequency and the equation is:

where,
is the wavelength, c is the speed of light and
is frequency.
Frequency is
and the speed of light is
.
Since, 
So, 
Let's plug in the values in the equation:


Hence, the right option is D)
.
