Which option wrongly understands the behavioural nature of management principles?

Correct answer: They only explain the speed of machines

The behavioural nature of management principles means that these principles are concerned with people, their actions, relationships, motivation and responses inside an organisation. They influence how managers behave and how employees perform their work, but they do not deal exclusively with the technical speed of machines. A machine may be involved in production, yet management principles focus on organising people and resources rather than describing machine movement alone. Thus, option C is the incorrect understanding and is the correct answer to this question. Options A, B and D are consistent with the behavioural nature because management is carried out through people and affects their behaviour and work.
