Final answer:
The correct answer is option B. Human Skills and C. Conceptual Skills.
Step-by-step explanation:
As managers rise through the managerial ranks, the types of skills that increase in importance are primarily human skills and conceptual skills. Technical skills are essential at the lower levels of management where the focus is on the direct application of knowledge and expertise to specific tasks and processes. Human skills, which involve the ability to work well with others, are crucial throughout all levels of management but become increasingly important as managers take on more leadership and coordination roles.
Conceptual skills, on the other hand, become more vital as managers ascend to higher ranks, where they must engage in strategic thinking, problem solving, and decision-making that affect the entire organization. Managers are heavily responsible for a subordinate's job satisfaction and career development and require a broad vision to effectively steer their teams and the organization towards success.
