Answer:
The correct option is B: Specific and provided during the construction of the project, and the end of the project
Step-by-step explanation:
For a feedback to be considered effective, then it has to be specific; it has to be meaningful; it must be timely; and it should be candid and constructive. Another feature of an effective feedback is that it should be about the process. Hence it is important for Marta to provide feedback when the graphic designer is in the process of his work. You don't want to wait till the end before you start providing feedback, as your feedback can help the person achieve a great result at the end of the project. Hence the reason for the option selected.
