D.
Concatenation
Answers
D.
Concatenation
Suggested answer: C

Explanation:

The data process describes the transformation of data in some way, either combining the data, reordering the data, converting the data, filtering the data, or other such activities.

Answer B is incorrect. An external entity is a source or destination of data. It is represented as a labeled rectangle.

Answer A is incorrect. Data flow identifies where data is being moved between a data process and an external entity, a data store or another data process.

Answer D is incorrect. Concatenation isn't a valid component of a data flow diagram so this choice is not valid.
