In which scenario can an approver recommend denial of an assignment?

The scenario where an approver can recommend denial of an assignment due to a lack of necessary information is justified because sufficient information is essential for making informed decisions. When an assignment lacks the necessary details, it can create ambiguity and uncertainty, which may lead to improper execution or confusion regarding the task's requirements. An approver needs comprehensive information to evaluate the assignment's viability, determine resource allocation, and ensure that all aspects have been considered. Denying the assignment in this case is a responsible action to prevent potential issues arising from insufficient data, which could impede workflow or lead to project failures.

In contrast, the other scenarios do not align with the rationale for denial based on information insufficiency. An absence of response to inquiries or the assignment exceeding an allowed time frame may not independently warrant denial, depending on the context and any mitigating factors that might be in play. A feasible assignment, by definition, should not be denied; it lacks any basis for rejection. Thus, the appropriateness of denying an assignment hinges on the critical need for necessary information for sound decision-making.
