Timothy needs to present some complex concepts to company executives that involve processes and transformations in action. He tried doing this using charts and textual data, but his manager feels another medium would be more effective for his needs. Timothy should use ________.

A) line charts to show the stages of the process
B) a flowchart to explain the process
C) animation or videos to show the processes and transformations in action
D) photographs to give a realistic picture of the elements of the process

Animation or videos are the best choice for showing processes and transformations in action as they provide a more interactive and engaging visual representation of the concepts. This helps the executives to understand the concepts more easily than textual or pictorial data. Line charts and flowcharts are good for explaining the stages and steps involved in the process, but they may not adequately demonstrate the transformations happening within the process. Photographs may also provide a realistic picture of the elements in the process, but they may not illustrate the flow of the process itself.
