Question
What is the relationship between a Bel and a decibel (dB)?
Correct Answer
Option A is the correct answer.
Detailed Explanation
The text explicitly states, 'The decibel (dB), one-tenth of a Bel, is more often used as the unit of measurement.' If a decibel is one-tenth of a Bel, then one Bel must be equal to ten decibels.
Hint
Recall the meaning of the prefix 'deci-' in units of measurement.
