Which Post permission setting allows you and anyone you select (such as an assistant teacher) to send messages to the group?

The Post permission setting that allows you and anyone you select, such as an assistant teacher, to send messages to the group is linked to the role of group owners. Owners typically have the highest level of control over a group, which includes the ability to manage the group's settings and permissions. This role can delegate message-sending privileges to others, such as co-teachers or assistants, enabling a collaborative communication environment within the group.

In this context, the owners have the flexibility to decide who can post messages through their authority to add or manage members. This capability is particularly useful in educational settings where collaboration is crucial, as it allows for quick dissemination of information and support among educators working together.

The other options present different levels of permissions that do not encompass the same breadth of control or ability to designate posting privileges to others in the group.
