When Writing Information in the Plan Section of the SOAP

When writing information in the plan section of the SOAP note, why is it important to provide sufficient information?

A) So another therapist can reproduce the treatment session if the first therapist is absent
B) So the therapist can determine if the patient is progressing toward the goals outlined in the evaluation over the time period outlined
C) So the therapist can answer all of the patient's questions about each treatment session
D) So the patient can tell his or her family what the treatment session included
