Please answer question 3 and why is it that option. Thank you. 

**Educational Website Content** ### Amplitude Modulation and Receiver Functions **1. Amplitude Modulation Formula** In the following formula for a sine wave, which variable is manipulated by the intelligence signal to produce amplitude modulation? \[ v = V_P \sin(\omega t + \Phi) \] - a) \(V_P\) - b) \(\omega\) - c) \(t\) - d) \(\Phi\) **2. Audio Section Functionality in Sensitive Receivers** The function that turns off the audio section in a sensitive receiver when it has no carrier is: - a) Delayed AGC - b) Auxiliary AGC - c) Squelch - d) Intermod **3. Modulation Index of a Waveform** The waveform diagrammed below has a modulation index that is: ![Waveform Diagram](waveform.png) - a) zero - b) greater than zero but less than one - c) equal to one - d) greater than one **Explanation of the Diagram**: The waveform diagram shows multiple cycles of a signal that fluctuates in amplitude. The modulation index, a measure of the extent of modulation, determines how much the amplitude of the wave changes in relation to its original amplitude.
