A principal who allows teachers the freedom to organize activities as they like demonstrates a leadership style characterized by minimal intervention and maximum autonomy for the team.

A principal who allows teachers the freedom to organize activities as they like demonstrates a leadership style characterized by minimal intervention and maximum autonomy for the team.

Let's evaluate the options:

• Autocratic style: The leader makes all decisions and gives direct orders, offering no freedom. This is incorrect.
• Situational style: The leader adapts their style based on the specific situation and the team's readiness. While it involves flexibility, the core of the description is about consistent freedom, not adaptation. This is incorrect.
• Democratic style: The leader involves the team in decision-making through consultation and collaboration. While it offers participation, "allowing freedom to organize any activities they like" suggests even more hands-off approach than typical democratic leadership. This is less fitting.
• Authoritative style: The leader sets a clear vision and expectations but still maintains control and directs the team. This is incorrect.
• Laissez-faire style: This style is characterized by a "hands-off" approach, where the leader provides little to no direction and allows team members complete freedom and autonomy in their work. This perfectly matches the description of the principal.

The final answer is $\text{5. laissez-faire leadership style}$
