The most likely cross-section shape of a cotton fibre is (C).
- The cotton fibre is not a good reflector.
- It has an irregular surface due to which the light rays falling on it gets reflected randomly in all the directions.
- They will not be reflected as parallel beams of light.
- Out of the given options, only option (C) reflects light in such a manner, so it is the correct option.
