Explanation:
(a) The sound with the lowest amplitude is not specified in the given table, so I cannot determine which sound has the lowest amplitude based on the information provided.
(b) The table does not provide information about the intensity of the sound of ringing of a telephone and the sound of talking. Therefore, I cannot compare the intensities or explain the difference.
(c) Among the given options, the sound with 90 dB has the highest intensity. Intensity is directly proportional to the square of the amplitude of the sound wave.
