Answer: B. Wave A is louder than Wave B.
Explanation: The loudness of sound is measured in unit called decibels (dB).
A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.
Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.
Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.
