The multimedia element that Samuel should use to display live assembling of the product's parts is 1- video.
While both video and animation can be used to demonstrate how to assemble a product, video is generally more effective for live demonstrations. Video can capture the actual process of assembling the product in real-time, which can be helpful for viewers who want to follow along and assemble the product themselves.
Animation, on the other hand, is better suited for illustrating complex processes or concepts that are difficult to demonstrate in real-time. Animation can be used to break down the assembly process into smaller steps, highlight important details, and provide a more detailed view of the product's parts and how they fit together.
