What does LASER stand for?

Explanation:
The main concept here is the exact phrase LASER stands for and the precise wording of its expansion. LASER stands for Light Amplification by Stimulated Emission of Radiation. The best option includes every word in that order, with the prepositions “by” and “of” included, starting with Light and ending with Radiation. This preserves the true meaning: light is amplified through stimulated emission of radiation. The other options omit or alter words (missing “by” or “of,” or starting with Laser instead of Light), which changes the exact expansion and makes them incorrect.
