Final answer:
An undergraduate student is one who is pursuing a Bachelor's or an Associate's degree. To become a psychology professor, one would typically need to progress from an undergraduate degree in psychology to completing a Master's and eventually a PhD.
Step-by-step explanation:
An undergraduate student is someone who is pursuing either A. Bachelor's degree or D. Associate's degree. Undergraduate education encompasses different forms of post-secondary education that lead to an Associate's degree, which is typically earned at community or technical colleges, and a Bachelor's degree, which is awarded after completing a four-year college program. In contrast, B. Master's degree and C. Doctoral degree are considered postgraduate or graduate degrees.
For someone aiming to become a psychology professor at a 4-year college, advanced education beyond an undergraduate degree is necessary. The progression typically starts with earning an undergraduate degree, such as a bachelor of science or a bachelor of art in psychology. Most professorial positions require further education; therefore, after acquiring a bachelor's degree, the individual would likely need to pursue a master's degree and eventually a PhD in psychology to develop the expertise and qualify for a professorship.
