Marks: +1, -0

An initially parallel cylindrical beam travels in a medium of refractive index µ(I)=µ0+µ2I, where µ0 and µ2 are positive constants and I is the intensity of the light beam. The intensity of the beam is decreasing with increasing radius.
The speed of light in the medium is

minimum on the axis of the beam
the same everywhere in the beam
directly proportional to the intensity I
maximum on the axis of the beam
