Which mapping tool allows for collaboration and sharing within Google Drive?

Google My Maps is the correct choice because it is specifically designed for users to create custom maps that can be shared and collaborated on with others. This tool allows individuals to add markers, shapes, and directions to a map, and users can invite others to edit or view these custom maps, facilitating collaborative planning and information sharing.

In contrast, Google Maps primarily provides navigation and location services but lacks features for custom map creation and collaboration. Google Earth, while also an engaging mapping tool, focuses more on geographical exploration and visualization rather than collaborative mapping projects. Google Photos, on the other hand, is dedicated to photo storage and sharing, making it unrelated to the mapping context. Therefore, Google My Maps stands out for its tailored features that support collaboration and sharing within Google Drive.
