B、Requiring signatures to confirm receipt of goods or services
C、Sequential numbering of transaction documents
D、Authorisation policies
【参考答案及解析】
Rationale: This should be clear from the context, because of the collusion with customers (if you remembered what collusion was). Physical security refers to keeping assets under lock and key: not to be dismissed as a fraud prevention measure! Sequential numbering works because it is easy to spot if documents are missing. Authorisation policies increase checks and accountabilities.
