This is not an advanced rule governing data flow diagramming. In fact, composite data flows on one level can be split into component data flows at the next level. The other options are all advanced rules for DFDs. A) To avoid having data flow lines cross each other, data stores may be repeated on a DFD. B) At the lowest level of DFDs, new data flows may be added to represent data that are transmitted under exceptional conditions. D) The inputs to a process must be sufficient to produce the outputs from the process.
