A

Wavelength is longer than wavelength of visible light; time taken is 15 minutes15\text{ minutes}15 minutes

B

Wavelength is longer than wavelength of visible light; time taken is much less than 15 minutes15\text{ minutes}15 minutes

C

Wavelength is shorter than wavelength of visible light; time taken is 15 minutes15\text{ minutes}15 minutes

D

Wavelength is shorter than wavelength of visible light; time taken is much more than 15 minutes15\text{ minutes}15 minutes
