Final answer:
A transformational leader is the most likely to have a long-lasting positive impact on their country, as they inspire change and motivate followers to work towards the collective good, balancing vision with the capacity to implement sustainable change.
Step-by-step explanation:
Of the different leadership styles listed, a transformational leader is most likely to enact the kind of changes that would benefit their country long-term. Transformational leaders are proactive, create and inspire visions of the future, and motivate their followers to exceed their own self-interests for the good of the group and society. They seek to transform the status quo to achieve progressive and positive change. An authoritarian leader typically has a top-down communication pattern, often resulting in quick decision-making but sometimes at the expense of group morale and creativity. A laissez-faire leader may be too hands-off, risking a lack of progress and group dissolution. While charismatic leaders can be compelling and inspire passionate followings, their influence often does not last. They can bring about significant change, yet it may not be enduring. Moreover, their reliance on personal magnetism rather than enduring institutions or policies can lead to instability once they leave the scene.
