Which two options are examples of metadata?

Metadata refers to data that provides information about other data. It serves to describe the content, quality, condition, and other characteristics of data files. The option that refers to both a raster dataset and an MP3 file size correctly embodies this concept because:

• A raster dataset includes extensive metadata that describes the geographical extents, resolutions, pixel sizes, and coordinate systems used. This enables users to understand how to properly use and interpret the raster data.

• The MP3 file size conveys important information about the file itself, such as storage requirements and quality, which informs users about how much space it will occupy, as well as potential limitations regarding playback devices and streaming capabilities.

In combination, these components provide a clear example of metadata: one informs about the geographical data characteristics and the other about the audio file's attributes, both essential for understanding their respective data types.
