When ultraviolet rays pass through the atmosphere, the vibration frequency of the ozone layer can just resonate with the ultraviolet rays, so that this vibration absorbs most of the ultraviolet rays. Therefore, the resonance energy can make the ozone layer in the atmosphere like sunscreen oil, which guarantees us Injured by rays. What best summarizes the central idea above? ['The ozone layer protects us from UV rays.', 'UV and resonance.', 'Where did the UV rays go?', 'Resonance protects us from UV rays.']
