Solution

The correct option is B monochromatic and coherent.
As mentioned in the passage, LASER produces coherent light by population inversion. Since there is only one transition that takes place to emit light, that is, that from meta-stable state to ground state, light corresponding to only one energy is emitted. Thus the LASER light is monochromatic.
