As we learned

 

 

Interference of light waves -

In order to observe interference in light waves, the following conditions must be met:

  •  The sources must be coherent.i.e Two sources are said to be coherent if they produce waves of the same frequency with a constant phase difference.  
  • The source should be monochromatic (that is, of a single wavelength).

 So option C is correct.
