What type of content falls under the definition of digital assets?

Digital assets encompass any content that exists in a digital format and can be stored, shared, and accessed electronically. This includes a broad range of media types that are commonly utilized in creative and digital media sectors. The correct answer accurately identifies images, videos, and documents, which are all quintessential forms of digital assets. These assets can be utilized for various purposes, such as marketing, content creation, and communication, making them vital in today's digital landscape.

The other options do not fit the definition of digital assets as they either refer to non-digital items, like physical products, or limit the definition to specific formats, such as only text-based documents, which excludes a vast array of valuable digital content. Additionally, while interactive systems and applications may contain digital assets within them, they themselves are not categorized as digital assets in the same broad context. The correct option effectively captures the essence of digital assets.
