maintains consistency among a set of DFDs by ensuring that input and output data flows align properly. A. Terminating B. Functioning C. Leveling D. Balancing

D. Balancing

Explanation:

The concept of balancing states that all the incoming flows to a process and all the outgoing flows from a process in the parent diagram should be preserved at the next level of decomposition.  Process decomposition lets you organize your overall DFD in a series of levels so that each level provides successively more detail about a portion of the level above it.

The goal of the balancing feature is to check your system internal consistency, which is particularly useful as different levels of expertise are generally involved in a project.
