Final answer:
The final responsibility for forming the organization's mission lies with the top-management team.
Step-by-step explanation:
The final responsibility for forming the organization's mission lies with the top-management team. While the CEO plays a significant role in setting the direction of the organization, it is ultimately the top-management team who collaboratively define the mission and ensure its alignment with the organization's goals and objectives.
For example, in a company, the CEO may have the authority to make decisions, but it is the top-management team consisting of department heads, senior executives, and other key stakeholders who collectively shape the organization's mission by considering various factors such as market trends, customer needs, and organizational resources.
Therefore, in this context, the correct answer is b. top-management team.
