Step 1: Set up the two conditions in the question.
The situation calls for (a) quick decisions and (b) managing inexperienced subordinates. We need a leadership style that handles both at once.
Step 2: Evaluate Democratic leadership.
Democratic leadership involves consulting team members and building consensus before deciding. This takes time and works well when the team is experienced and their input is valuable. It is too slow for emergencies.
Step 3: Evaluate Free-Rein (Laissez-Faire) leadership.
Here the leader steps back and gives team members complete freedom. This demands that the subordinates are highly skilled and self-directed. With inexperienced workers, a hands-off approach would cause chaos.
Step 4: Evaluate Transformational leadership.
Transformational leadership focuses on inspiring long-term change and growth. It is a vision-oriented style suited for nurturing talent over time, not for making rapid on-the-spot decisions.
Step 5: Evaluate Autocratic leadership.
An autocratic leader keeps decision-making authority entirely to themselves, issues clear instructions, and expects compliance. This removes the delay of consultation and gives clear direction to workers who lack the experience to act independently.
Step 6: Confirm the answer.
When speed and clear top-down direction are critical, autocratic leadership is the most suitable style.
\[ \boxed{ \text{(B) Autocratic} } \]
