The correct answer is: A. Harold Koontz
Harold Koontz was an American management theorist and author. He is best known for his work on the principles of management, and for his co-authorship of the book “Principles of Management” with Cyril O’Donnell.
Koontz was born in 1909 in Colorado Springs, Colorado. He received his bachelor’s degree from the University of Denver in 1931, and his master’s degree from the University of California, Berkeley in 1932. He then worked as a management consultant for several years before joining the faculty of the University of California, Los Angeles in 1939.
Koontz retired from UCLA in 1972, but continued to write and consult until his death in 1996. He is considered one of the most influential management theorists of the 20th century.

- B. Teery is not a well-known management theorist.
- C. Louis Allan is not a well-known management theorist.
- D. Hendry Fayol was a French mining engineer and business executive who is considered one of the founders of modern management theory. However, he did not write the book “General and Industrial Management.”
