In the context of Frederick W. Taylor's four principles of scientific management, which of the following is a difference between the first principle and the third principle?

a. In the first principle, managers are instructed to cooperate with employees to ensure the implementation of scientific principles, whereas in the third principle, managers are required to divide work and responsibility equally between management and workers.

b.The first principle is to develop a science for each element of work, whereas the third principle instructs managers to cooperate with employees to ensure that scientific principles are actually implemented.

c. In the first principle, managers are required to scientifically select, train, teach, and develop workers to help them reach their full potential, whereas in the third principle, managers are required to determine the best way to do work.

d. The first principle is to divide work and responsibility equally between management and workers, whereas the third principle guides managers to scientifically select, train, teach, and develop workers to help them reach their full potential.
