Final answer:
The correct answer is option d. At lower organizational levels, technical skills are of the utmost importance for performing specialized tasks effectively.
Step-by-step explanation:
In the context of organizational levels, each skill type plays a different role at various levels. At lower organizational levels, technical skills are most important. This is because employees at this level are typically responsible for operations involving specialized activities, and they need to have the specific technical abilities to perform these tasks effectively.
As one climbs the organizational ladder, the importance of planning skills, human skills, and conceptual skills grows. However, for entry-level and frontline tasks, having hands-on knowledge and the ability to directly apply it is essential, which is why technical skills take precedence at lower organizational tiers.
