Anthony disagrees with several minor details of the decision his group has reached, but he recognizes that most members of the group support the decision. if anthony decides not to start a debate over the details of the decision and begins, instead, to think about how the decision will affect his work in the future, which developmental stage has his group likely entered?

I believe the answer is: reinforcement development stage

During this stage, the behaviour would be strengthen and modified in away that make the person keep repeating the behaviour. Usually this behaviour is determined if the person who does it is aiming some sort of rewards or try to avoid some sort of punishment.

the answer might be either a or c. can't be too sure , because i searched the web, but no valid answers came through.
