Answer 1

Option "c" is the correct answer for the above question.

Step-by-step explanation:

The data flow diagram is a diagram that is designed by the designing phase os the SDLC. It is used to display the data flow to the developer or any other user, which wants to know the structure of the software. It has three steps- 0-level, 1-level, and 2-level.The above question asked about the DFD which is defined by the c option. This option states the DFD definition which is defined above. Hence the answer is option c, while the other option is not correct because:-

• Option 'a' states about the structure of Information technology.
• Option b states about the SDLC phase.
• Option d states about the flowchart.
