Dear student,
Beam is a group of light rays moving in an organised manner.
To artificially produce a light beam , lamp and parabolic reflector is used in many lighting devices such as spotlights,car head lights etc..
A ray of light is an idealized model of light, which is drawn as a straight line,if you draw a line that goes at 90 degrees to those peaks and troughs, you get a ray pointing in the direction the energy is flowing.
Option A is correct.
