A B C DAnswer: # Explanation:## Step 1: Understanding the problemThe question is about the graphical representation of an alternating potential difference, which is the voltage in an alternating current (AC) circuit. In an AC circuit, the voltage changes direction periodically, and this is typically represented as a sinusoidal wave.## Step 2: Analyzing the optionsWe need to identify which of the diagrams (A, B, C, or D) correctly represents an alternating potential difference. Since we know that an alternating potential difference is represented by a sinusoidal wave, we are looking for a diagram that shows a wave that oscillates above and below a central line (representing zero voltage).# Answer: [The diagram that shows a sinusoidal wave]
