Correct Answer: D

A context data flow diagram (DFD) helps SMEs understand the complexity of their request and provides a good starting point for detailed analysis. The “area of study” is solution independent and as such gives the analysts and SMEs the ability to envision multiple solutions. It is not used as a design specification, but as a visual depiction of scope.
