You need to configure a folder that allows everyone in your group to view and modify files. Which item in the Share With menu should you use?

Specific People requires individual user selection and does not inherently apply to an entire group with read/write access without further configuration.

Nobody prevents any sharing of the folder, making it inaccessible to all users.

Selecting Homegroup (Read/Write) ensures that all members of the configured Homegroup have both viewing (read) and modification (write) permissions for the shared folder and its contents.

Homegroup (Read) would allow viewing but not modification of files by group members, failing to meet the requirement for modifying files.
