Mike is a PM for an IT technology Implementation project. He is using an Ishikawa Diagram to figure out what could have caused  the potential risk in his project. which process describes this?

Options:

a) Risk Identification

b) Qualitative Analysis

c) Quality Control

d) Risk Response

I answered C because the question is saying "What could have caused" which means the problem already happened, I related "caused" to "defect".
