AI Explanation

The correct answer is A. A sinusoidal wave is a waveform that follows a sine curve, which is the shape shown in option A of the illustration EL-0088. This wave shape is characterized by its smooth, periodic oscillation, with a repeating pattern of crests and troughs. The other options, B, C, and D, depict different wave shapes that do not match the defining characteristics of a sinusoidal wave, such as rectangular or triangular waveforms. Therefore, A is the only correct answer among the choices provided.
