Final answer:
A manager addressing an environmental issue is acting in the role of a leader, as this aligns with leadership responsibilities of guiding and improving situations. An expressive leader is exemplified by the director of a summer camp for chronically ill children, who would prioritize group harmony and morale.
Step-by-step explanation:
If a manager takes responsibility for correcting an environmental problem that has been created by her company, she is acting in the role of a leader. This is because leadership involves guiding others to complete a set of tasks or to improve upon a situation, which in this instance includes addressing environmental concerns linked to the company's operations. Moreover, the notion of a leader in a business context often extends to taking charge during difficult situations and being the catalyst for positive change, reflecting the proactive and responsible approach needed to tackle environmental issues.
When we consider who is more likely to be an expressive leader, option c, "The director of a summer camp for chronically ill children," is a good example. Expressive leadership refers to those who focus on maintaining group harmony and morale, which would be essential in the context of a summer camp for children with chronic illnesses, where the emotional well-being of the participants is a key concern.
