Answer:
The observer detects light of wavelength is 115 nm.
(b) is correct option

Given that,
Wavelength of source = 500 nm
Velocity = 0.90 c
We need to calculate the wavelength of observer
Using Doppler effect
Where, 
Hence, The observer detects light of wavelength is 115 nm.
The answer would be C. Gamma Rays and High Frequency EM waves travel at the speed of light and are transverse waves.
