Vedclass · Answer

(D) . Laser beams are highly directional and possess a high degree of parallelism. Because of this,they remain as a very narrow beam even over long distances without significant spreading or divergence. While monochromaticity and coherence are fundamental properties of lasers,it is their high degree of parallelism that specifically enables them to be used for precise long-distance measurements.
