Answer:
C) keeping an open mind.
Step-by-step explanation:
Ricardo showed a great example of how to be open-minded about work. As seen in the text above, Ricardo was replaced in the project he was managing because he was having difficulties and his presence did not allow the project to move forward. Ricardo was aware that a new manager would be the best for the project to progress and so he accepted the replacement and showed the points where he had made mistakes, so that the new manager could resolve them. This shows how Ricardo is an open-minded person, willing to act according to what is best for his projects.
