The correct answer is: D. There is great difference between management and administration.

Henry Fayol was a French mining engineer and business executive who developed a general theory of business administration that is often called Fayolism. He is widely considered to be one of the founders of modern management theory.

Fayol defined management as "the art of getting things done through people". He identified five functions of management: planning, organizing, commanding, coordinating, and controlling. He also developed 14 principles of management, which are still widely used today.

Fayol believed that there was a clear distinction between management and administration. He defined administration as "the function that ensures that everything is done in the best possible way". He argued that administration is concerned with the overall direction of an organization, while management is concerned with the day-to-day running of an organization.

Fayol's distinction between management and administration has been criticized by some scholars. They argue that there is no clear line between the two functions, and that they are often intertwined. However, Fayol's work remains influential in the field of management, and his principles are still widely used today.

Here is a brief explanation of each option:

  • A. Management is a part of administration. This option is incorrect because Fayol believed that management and administration are two distinct functions.
  • B. Administration is a part of management. This option is also incorrect because Fayol believed that management and administration are two distinct functions.
  • C. There is no difference between management and administration. This option is incorrect because Fayol believed that management and administration are two distinct functions.
  • D. There is great difference between management and administration. This option is correct because Fayol believed that management and administration are two distinct functions.
