The Textbook Notes That the Division Between Industrial and Organizational

The textbook notes that the division between industrial and organizational psychology is somewhat artificial. What is one reason the textbook provides for why this might be a false dichotomy?

A) Nobody in the field can agree on what is meant by "industrial" versus "organizational" psychology.
B) Few organizations are concerned with industrial psychology topics, so nearly all I/O psychology consultants address only organizational topics.
C) When I/O psychologists take their licensure exams, they have to answer questions about both industrial and organizational topics.
D) I/O psychologists are trained in both topics, even though they may specialize in one or the other.
