Whose principles can be modified according to the situation?

Management principles

The correct answer is option 2- Management principles.

Management principles can be modified according to the situation.
Since the principles of management are not as exact as the principles of science, their application and use are not universal. They have to be modified according to a given situation. However, they provide managers with certain standardised techniques that can be used in different situations. These principles are also used for training and development of managers.

In contrast, scientific principles (or science principles) are universal and do not change with situations. Hence, only management principles fit the requirement.
