The correct answer is D. implicit policy.
An implicit policy is a policy that is not explicitly stated, but is inferred from the behavior of the superior. For example, if a superior always arrives at work late, it can be inferred that they are not enforcing a strict policy on punctuality.
A specific policy is a policy that is explicitly stated and is not open to interpretation. For example, a policy that states that employees must arrive at work by 9:00 am is a specific policy.
An external policy is a policy that is imposed by an outside agency, such as the government. For example, a policy that requires all businesses to provide paid sick leave is an external policy.
An appealed policy is a policy that has been challenged and is currently being reviewed by a higher authority. For example, a policy that requires all employees to undergo a drug test may be appealed by an employee who believes that the policy is discriminatory.
