The correct answer is: Position power
Rationale: Position power is legitimate organisational authority, by virtue of a position in the organisation hierarchy: managers depend largely on it for their influence.
Leaders are often required to exercise informal, interpersonal forms of influence, such as person power (charisma, inspiration) and expert power (valued knowledge).
Physical power (intimidation) should be used by neither managers nor leaders!
Pitfalls: the classifications of power are a rich source of related terminology, and hence a potential source both of confusion - and of exam questions!
