Roan and Paul Decided to Organize a Reunion of All

Roan and Paul decided to organize a reunion of all their old classmates living in and around New York City. After inviting everyone, they decided on a date and venue. A few days later, Maria, one of the invitees, informed them that she would not be able to make it on that particular day but was free the next day. They were disappointed to hear this but decided to go ahead with the plan anyway. In the context of research on relational values, their degree of acceptance of Maria can be described as that of:

A) maximal inclusion.
B) active inclusion.
C) passive inclusion.
D) ambivalence.
