Hi! Can someone help me with these CFA question.

Andrea, Daniel and Mauricio are three colleagues in an investment advisory firm who have been studying for the CFA designation over the last few years and are at various stages of the program. Andrea and Daniel have just registered to take the Level II examination, while Mauricio successfully passed his Level III examination a few months ago. In his promotional material which Mauricio designs for the firm he states of himself that Mauricio is a Chartered Financial Analyst with deep knowledge of the Oil and Gas sector. Andrea uses a business card which reads Andrea Gomez, CFA Level I and Daniel states in his promotional material that he has completed Level I of the CFA Program.
