Delegation of authority in an organisation is:

Compulsory

The correct answer is option 2- compulsory.

Delegation refers to the downward transfer of authority from a superior to a subordinate. It is a pre-requisite to the efficient functioning of an organisation because it enables a manager to use his time on high priority activities. It also satisfies the subordinate’s need for recognition and provides them with opportunities to develop and exercise initiative. Delegation is a compulsory act because no individual can perform all tasks on his own. It is a process followed to share tasks.
