题干中提到“When required the perform Integrated Change Control Process”，即当需要进行综合变更控制过程时。接着描述了“Which is a formally chartered group responsible for reviewing, approving, deferring or rejecting changes to the project and for coordinating and communicating such decisions”，这是一个正式授权的小组，负责审查、批准、推迟或拒绝项目的变更，并协调和传播这些决定。这与选项B中的“CCB”相符，因此答案是B。
