The correct answer is B. Vincent has a graduate degree.
Explanation:
Salary varies according to multiple factors that include the company you are working for, the position you have, and your experience or education. In the case of education, master's and doctoral's degrees are related to higher salaries, this occurs because these educational programs can only be completed after a bachelor's or similar degree, and are considered as graduate/professional degrees. On the other hand, undergraduate degrees including a bachelor or associate degree have lower salaries than graduate degrees because they involve less education and are completed after high school.
This implies the person that is likely to draw the highest salary is Vincent because he has a graduate degree that is superior to undergraduate degrees such as bachelor's or associate's degrees and high school diplomas.
