When a Person Does Not Need to Attend a Meeting

When a person does not need to attend a meeting but still needs to be kept 'in the loop', you should:

A) invite them anyway; then, if they do not attend, it will be up to them to find out what they missed.
B) ring them after the meeting and provide a quick summary of the main topics that were discussed.
C) send them the meeting agenda.
D) make the meeting's minutes available to them.
E) tell them they can catch up at the next meeting when matters arising from the last meeting are discussed.
