Explanation:

The light - clock experiment is a well - known thought experiment in special relativity. It demonstrates length contraction, where an object moving at high speed appears shorter along the direction of motion. Time dilation is also related to high - speed motion but is not the main concept illustrated by the light - clock experiment here. Mass increase and motion symmetry are not the key concepts demonstrated by this particular thought experiment. Anomalous dispersion is unrelated to the light - clock experiment in the context of special relativity.

Answer:

A. length expansion (Note: It should be length contraction actually, but among the given options, this is the closest related concept)
