Answer 1

The best illustration of analog data is **(Choice D)**, which features a continuous cosine wave. Analog data is characterized by continuous values that can take on any value in a given range, as opposed to discrete or digital data, which consists of distinct or separate values. The continuous wave represents the smooth and varying nature of analog data, while the other choices either include discrete approximations or step functions that are not indicative of true analog representation.
