Peak-to-peak amplitude is _____ the value of the amplitude.

Explanation:
The concept being tested is how peak-to-peak relates to the single-sided amplitude. For a waveform that swings from +A to -A, the highest point is A above the center and the lowest point is A below the center. The distance from top to bottom is A - (-A) = 2A. So the peak-to-peak value is twice the amplitude. This holds even if there’s a DC offset, since the top and bottom shift together but the difference remains 2A.
